ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.4/2.6.4-mm2/
- Added the new per-address_space block unplugging code. This is designed
to reduce the locking contention against the global plug list's lock and it
also allows us to avoid unplugging all the queues in the machine when we
want just a single queue to kick off its I/O.
- Reiserfs updates: mainly new features.
- Some significant NFS client enhancements: reads smaller than PAGE_SIZE
are no longer synchronous, support for smaller-than-PAGE_SIZE reads, etc.

+/*
+ * "Optimize" a list of dependencies as spit out by gcc -MD
+ * for the kernel build
+ * ===========================================================================
+ *
+ * Author Kai Germaschewski
+ * Copyright 2002 by Kai Germaschewski <[email protected]>
+ *
+ * This software may be used and distributed according to the terms
+ * of the GNU General Public License, incorporated herein by reference.
+ *
+ *
+ * Introduction:
+ *
+ * gcc produces a very nice and correct list of dependencies which
+ * tells make when to remake a file.
+ *
+ * To use this list as-is however has the drawback that virtually
+ * every file in the kernel includes <linux/config.h> which then again
+ * includes <linux/autoconf.h>
+ *
+ * If the user re-runs make *config, linux/autoconf.h will be
+ * regenerated. make notices that and will rebuild every file which
+ * includes autoconf.h, i.e. basically all files. This is extremely
+ * annoying if the user just changed CONFIG_HIS_DRIVER from n to m.
+ *
+ * So we play the same trick that "mkdep" played before. We replace
+ * the dependency on linux/autoconf.h by a dependency on every config
+ * option which is mentioned in any of the listed prequisites.
+ *
+ * To be exact, split-include populates a tree in include/config/,
+ * e.g. include/config/his/driver.h, which contains the #define/#undef
+ * for the CONFIG_HIS_DRIVER option.
+ *
+ * So if the user changes his CONFIG_HIS_DRIVER option, only the objects
+ * which depend on "include/linux/config/his/driver.h" will be rebuilt,
+ * so most likely only his driver ;-)
+ *
+ * The idea above dates, by the way, back to Michael E Chastain, AFAIK.
+ *
+ * So to get dependencies right, there two issues:
+ * o if any of the files the compiler read changed, we need to rebuild
+ * o if the command line given to the compile the file changed, we
+ * better rebuild as well.
+ *
+ * The former is handled by using the -MD output, the later by saving
+ * the command line used to compile the old object and comparing it
+ * to the one we would now use.
+ *
+ * Again, also this idea is pretty old and has been discussed on
+ * kbuild-devel a long time ago. I don't have a sensibly working
+ * internet connection right now, so I rather don't mention names
+ * without double checking.
+ *
+ * This code here has been based partially based on mkdep.c, which
+ * says the following about its history:
+ *
+ * Copyright abandoned, Michael Chastain, <mailto:[email protected]>.
+ * This is a C version of syncdep.pl by Werner Almesberger.
+ *
+ *
+ * It is invoked as
+ *
+ * fixdep <depfile> <target> <cmdline>
+ *
+ * and will read the dependency file <depfile>
+ *
+ * The transformed dependency snipped is written to stdout.
+ *
+ * It first generates a line
+ *
+ * cmd_<target> = <cmdline>
+ *
+ * and then basically copies the .<target>.d file to stdout, in the
+ * process filtering out the dependency on linux/autoconf.h and adding
+ * dependencies on include/config/my/option.h for every
+ * CONFIG_MY_OPTION encountered in any of the prequisites.
+ *
+ * It will also filter out all the dependencies on *.ver. We need
+ * to make sure that the generated version checksum are globally up
+ * to date before even starting the recursive build, so it's too late
+ * at this point anyway.
+ *
+ * The algorithm to grep for "CONFIG_..." is bit unusual, but should
+ * be fast ;-) We don't even try to really parse the header files, but
+ * merely grep, i.e. if CONFIG_FOO is mentioned in a comment, it will
+ * be picked up as well. It's not a problem with respect to
+ * correctness, since that can only give too many dependencies, thus
+ * we cannot miss a rebuild. Since people tend to not mention totally
+ * unrelated CONFIG_ options all over the place, it's not an
+ * efficiency problem either.
+ *
+ * (Note: it'd be easy to port over the complete mkdep state machine,
+ * but I don't think the added complexity is worth it)

- * "Optimize" a list of dependencies as spit out by gcc -MD
- * for the kernel build
- * ===========================================================================
- *
- * Author Kai Germaschewski
- * Copyright 2002 by Kai Germaschewski <[email protected]>
- *
- * This software may be used and distributed according to the terms
- * of the GNU General Public License, incorporated herein by reference.
- *
- *
- * Introduction:
- *
- * gcc produces a very nice and correct list of dependencies which
- * tells make when to remake a file.
- *
- * To use this list as-is however has the drawback that virtually
- * every file in the kernel includes <linux/config.h> which then again
- * includes <linux/autoconf.h>
- *
- * If the user re-runs make *config, linux/autoconf.h will be
- * regenerated. make notices that and will rebuild every file which
- * includes autoconf.h, i.e. basically all files. This is extremely
- * annoying if the user just changed CONFIG_HIS_DRIVER from n to m.
- *
- * So we play the same trick that "mkdep" played before. We replace
- * the dependency on linux/autoconf.h by a dependency on every config
- * option which is mentioned in any of the listed prequisites.
- *
- * To be exact, split-include populates a tree in include/config/,
- * e.g. include/config/his/driver.h, which contains the #define/#undef
- * for the CONFIG_HIS_DRIVER option.
- *
- * So if the user changes his CONFIG_HIS_DRIVER option, only the objects
- * which depend on "include/linux/config/his/driver.h" will be rebuilt,
- * so most likely only his driver ;-)
- *
- * The idea above dates, by the way, back to Michael E Chastain, AFAIK.
- *
- * So to get dependencies right, there two issues:
- * o if any of the files the compiler read changed, we need to rebuild
- * o if the command line given to the compile the file changed, we
- * better rebuild as well.
- *
- * The former is handled by using the -MD output, the later by saving
- * the command line used to compile the old object and comparing it
- * to the one we would now use.
- *
- * Again, also this idea is pretty old and has been discussed on
- * kbuild-devel a long time ago. I don't have a sensibly working
- * internet connection right now, so I rather don't mention names
- * without double checking.
- *
- * This code here has been based partially based on mkdep.c, which
- * says the following about its history:
- *
- * Copyright abandoned, Michael Chastain, <mailto:[email protected]>.
- * This is a C version of syncdep.pl by Werner Almesberger.
- *
- *
- * It is invoked as
- *
- * fixdep <depfile> <target> <cmdline>
- *
- * and will read the dependency file <depfile>
- *
- * The transformed dependency snipped is written to stdout.
- *
- * It first generates a line
- *
- * cmd_<target> = <cmdline>
- *
- * and then basically copies the .<target>.d file to stdout, in the
- * process filtering out the dependency on linux/autoconf.h and adding
- * dependencies on include/config/my/option.h for every
- * CONFIG_MY_OPTION encountered in any of the prequisites.
- *
- * It will also filter out all the dependencies on *.ver. We need
- * to make sure that the generated version checksum are globally up
- * to date before even starting the recursive build, so it's too late
- * at this point anyway.
- *
- * The algorithm to grep for "CONFIG_..." is bit unusual, but should
- * be fast ;-) We don't even try to really parse the header files, but
- * merely grep, i.e. if CONFIG_FOO is mentioned in a comment, it will
- * be picked up as well. It's not a problem with respect to
- * correctness, since that can only give too many dependencies, thus
- * we cannot miss a rebuild. Since people tend to not mention totally
- * unrelated CONFIG_ options all over the place, it's not an
- * efficiency problem either.
- *
- * (Note: it'd be easy to port over the complete mkdep state machine,
- * but I don't think the added complexity is worth it)

- * This program takes autoconf.h as input and outputs a directory full

- *
- * Think of the configuration options as key-value pairs. Then there
- * are five cases:
- *
- * key old value new value action
- *
- * KEY-1 VALUE-1 VALUE-1 leave file alone
- * KEY-2 VALUE-2A VALUE-2B write VALUE-2B into file
- * KEY-3 - VALUE-3 write VALUE-3 into file
- * KEY-4 VALUE-4 - write an empty file
- * KEY-5 (empty) - leave old empty file alone

Looks pretty good, same benchmark as last time (though hopefully the
profiles look a little nicer--sorry David, I wasn't able to get qprof
working today).

Andrew,
I re-ran six copies of the direct_read_under test on an 8-proc
machine last night. All six tests saw uninitialized data.

It is possible to trigger mpage_writepages twice at the same time,
right? Say once from sync_sb_inodes and once from filemap_fdatawrite?
I'm assuming Daniel is hitting the same bug he reported before, a race
between ll_rw_block from ext3 data=ordered and sychronous writeback from
fsync or O_DIRECT.
Picture one proc in mpage_writepages with wbc->sync_mode ==
WBC_SYNC_NONE, and a second proc with sync_mod = WBC_SYNC_ALL. The file
in question has one dirty page and that one page is being written by
kjournald in a data=ordered flush.
The sync none proc gets to a page with a locked buffer being written by
ll_rw_block. It locks the page, calls test_clear_page_dirty, and then
calls writepage.
The sync all proc now calls pagevec_lookup_tag(PAGECACHE_TAG_DIRTY), no
pages are returned, so it returns.
The sync none proc gets to the buffer_locked check in
__block_write_full_page and properly retags the page with
PAGECACHE_TAG_DIRTY, but it's too late. The sync all proc has already
skipped the page.
That's my theory anyway...

OK, that can happen. Daniel had a fixlet for that and I assume he's
retrying that.
Not only can it happen with ext3, but also with any random filesystem which
does ll_rw_blk() of a random metadata block. sync_blockdev() can miss the
associated page. Conceivably this could leave I/O in flight after umount.
I'm thinking that the right thing to do here is to change submit_bh()
callers and ll_rw_block() to run set_page_writeback(bh->b_page) when they
start the buffer writeout and to do the run-around-the-buffer_heads thing
at I/O completion. Ho hum, that'll take a bit of work but at least it
kills off some exceptionalities.

A page may have a mix of writeback and dirty+non-writeback buffers. It
appears that the page-level writeback code will handle this correctly. But
it requires that the page lock be held when we run set_page_writeback(), so
that tears that. hmm.

I'll work this out yet.
We change the PageWriteback() predicate to go in and see if any of the
buffer_heads are under I/O too. And we change wait_on_page_writeback() to
also wait on any buffer_heads.
That means two new silly address_space ops. Or a new page flag which means
"the thing at ->private is buffer_heads". Probably the latter.

If buffer_heads are in flight and a SYNC_NONE writeback happens,
will checking the buffer_heads cause to writeback to block?

wait_on_page_writeback_range() does a pagevec_lookup_tag on
min(end - index + 1, (pgoff_t)PAGEVEC_SIZE)
Which translates to: (unsigned long)-1 - 0 + 1, which is 0.
It doesn't look like anyone is using the range feature of this function,
can we make it just wait on all the writeback pages?

We could, but there are the dreaded "future plans". In several places
we're syncing the whole file unnecessarily. Most notably, O_SYNC writes.
I'd like to get us to the stage where an O_SYNC write writes and waits upon
just the pages which are within the range of the caller's write(), without
holding i_sem.

Looks good, but I'm still having problems convincing pagevec_lookup_tag
to return anything other than 0 when called from

Well, that's certainly a lot slower ;-) I've got a direct_read_under
round going. While you're at it, there's one more bug.
The wbc struct used by filemap_fdatawrite doesn't initialize
wbc.nonblocking to zero. stack magic might give us a 1 there, leading
to an early exit from mpage_writepages even when doing a WB_SYNC_ALL.

I hope not.
static int __filemap_fdatawrite(struct address_space *mapping, int sync_mode)
{
int ret;
struct writeback_control wbc = {
.sync_mode = sync_mode,
.nr_to_write = mapping->nrpages * 2,
};
When you initialise some of the structure in this way the compiler will
zero out all the other fields.
(gets worried)
yup.
struct thing {
int a;
int b[1000];
};
foo()
{
int a[1000];
memset(a, 1, sizeof(a));
}
bar()
{
struct thing t = {
.a = 1
};
int i;
for (i = 0; i < 1000; i++) {
if (t.b[i]) {
printf("bad\n");
return;
}
}
}
zot()
{
struct thing t;
int i;

Yes, my brain wandered off for a bit. Seems like it's break time for
chris...good news is that direct_read_under is still running without

Here also, but _without_ clear_page_dirty_for_io.patch, so it should break.
Maybe it takes a long time.

It was very irregular for me. A run might die in pass3 or last for 30
minutes before I got bored and hit ctrl-c
-chris
I'm running without clear_page_dirty_for_io.patch on an 8-proc
with 6 direct_read_under tests on ext3.
2 failed in less than 5 minutes. The 4 others are still running
and it's been over 30 minutes.
I'll run overnight wth clear_page_dirty_for_io.patch added in.

Sorry I'm falling behind... I see about a 10% decrease in throughput
with our dbt2 workload when comparing 2.6.4-mm2 to 2.6.3. I'm wondering
if this might be a result of the changes to the pagecache, radix-tree
and writeback code since you mentioned it could affect i/o scheduling in
2.6.4-mm1.
PostgreSQL is using 8KB blocks and the characteristics of the i/o should
be that one lvm2 volume is experiencing mostly sequential writes, while
another has random reading and writing. Both these volumes are using
ext2. I'll summarize the throughput results here, with the lvm2 stripe
width varying across the columns:
kernel 16 kb 32 kb 64 kb 128 kb 256 kb 512 kb
2.6.3 2308 2335 2348 2334
2.6.4-mm2 2028 2048 2074 2096 2082 2078
Here's a page with links to profile, oprofile, etc of each result:
http://developer.osdl.org/markw/linux/2.6-pagecache.html
Comparing one pair of readprofile results, I find it curious that
dm_table_unplug_all and dm_table_any_congested show up near the top of a
2.6.4-mm2 profile when they haven't shown up before in 2.6.3.
Mark
I'm ran 2.6.4-mm2 plus the 2 wait_on_page_range() patches,
the test_set_page_writeback() patch and clear_page_dirty_for_io patch
overnight.
6 copies of direct_read_under test on 8-cpu system on 1
ext3 file system in 1 directory on a scsi disk.
(http://developer.osdl.org/daniel/AIO/TESTS/direct_read_under.c)
5 of the 6 tests saw uninitialized data within 2 hours.
The sixth test ran overnight.

Could be. Have you run tests without LVM in the picture?

That's broken. How many disks are involve in the DM stack?
The relevant code was reworked subsequent to 2.6.4-mm2. Maybe we fixed
this, but I cannot immediately explain what you're seeing here.

Do you still have the errors generated? I wondering how big the range
of uninitialized data was. When I was bug hunting yesterday, I saw
ranges from 64k to 32mb in size, which was why I decided writes weren't
getting to the disk at all.
It might be interesting to try with data=writeback, or on ext2. Things
might be easier to track if we're not worried about ll_rw_block.
It might also be interesting to significantly lower the size of the
reads and writes done by direct_read_under, or anything else you can
think of to get the reproduce time down to something smaller than 2
hours...
It's probably a good idea to upgrade to 2.6.5-rc1-mm2, just so we're all
staring at the same code.

No I haven't and I'm hesitant to. I have 52 single drives in one volume
and 14 single drives the other. Because it's PostgreSQL, my options are
to either run on a single drive (and not be able to drive the system as
hard) or to reconfigure my drives using hardware raid. I could do the
latter if you think it'll help. It's just a bit time consuming.

It might be more valuable to retest on 2.6.5-rc1-mm2. I'm assuming
postgres was doing synchronous writes, and 2.6.4-mm2 doesn't really wait
correctly.

Chris,
Still have the data:
63 pages (258048 bytes)
90 pages (368640 bytes)
139 pages (569344 bytes)
30 pages (122880 bytes)
87 pages (356352 bytes)
I'm rebooting to 2.6.5-rc1-mm2 and will re-run. I have do have
versions of direct_read_under that do smaller i/o and also
1 that does forks off and does 'sync' calls every few seconds.
I'll give ext2 and try as well.

Ugh that looks really bad, I wonder how it could possibly ever be this
bad. Mark, please do do a run with 2.6.5-rc1-mm2, I'd very much like to
see the profile there. If things get this bad, I need to think some more
about how to best handle the 'when to invoke request_fn on unplug calls'
logic again.
Actually, please also do a run with 2.6.5-rc1-mm2 + inlined patch. For
non-stacked dm on dm it should work and could make a lot of difference
for you.

There are the results with 2.6.5-rc1-mm2 with your patch with a 512kb
stripe width. The throughput didn't improve but it did cut the ticks
for dm_table_unplug_all in half. Should I continue with smaller stripe
widths?

generic_unplug_device() is only sucking 0.5% of total CPU capacity, so
perhaps we need to be looking elsewhere for the source of the slowdown.
I suggest we do something like this:
--- 25/drivers/md/dm-table.c~a 2004-03-18 19:03:15.130004696 -0800
+++ 25-akpm/drivers/md/dm-table.c 2004-03-18 19:03:41.656971984 -0800
@@ -893,7 +893,7 @@ void dm_table_unplug_all(struct dm_table
struct dm_dev *dd = list_entry(d, struct dm_dev, list);
request_queue_t *q = bdev_get_queue(dd->bdev);
- if (q->unplug_fn)
+ if (q->unplug_fn && queue_needs_unplug(q)))
q->unplug_fn(q);
}
}
to reduce the computational expense of dm_table_unplug_all() a bit.
But we're barking up the wrong tree here. Mark, if it's OK I'll run up
some kernels for you to test.

I thought about this last night, and I have a better idea that gets the
same accomplished. The problem right now is indeed that we aren't
tracking who needs to be unplugged, like we used to. The solution is to
do the exact same style plugging (with block helpers) that we used to,
except the plug_list is maintained in the driver. So when you do
dm_unplug(), it doesn't _have_ to iterate the full device list, only
those that do need kicking.
I'll produce a patch to fix this this morning. First coffee.

Wait for a real patch first, I'll have one for you in an hour or two.

Yes, it would be nice but I fear that it gets complicated.
Is it not the case that two dm maps can refer to the same queue? Say, one
map uses /dev/hda1 and another map uses /dev/hda2?
If so, then when the /dev/hda queue is plugged we need to tell both the
higher-level maps that this queue needs an unplug. So blk_plug_device()
and the various unplug functions need to perform upcalls to an arbitrary
number of higher-level drivers, and those drivers need to keep track of the
currently-plugged queues without adding data structures to the
request_queue structure.
It can be done of course, but could get messy.
Or am I missing something?

That would get nasty, it's much more natural to track it from the other
end. I view it as a dm (or whatever problem) that they need to track who
has pending io on their behalf, which is pretty easy to to from eg
__map_bio().
The only addition is putting the old q->plug_list back, but using it on
stacking drivers like dm. dm then maintains a per-dm plugged list that
it can use when dm_unplug() runs.

But dm doesn't know enough. Suppose it is managing a map which includes
/dev/hda1 and I do some I/O against /dev/hda2 which plugs the queue. dm
needs to know about that plug.
Actually the data structure isn't toooo complex.
- In the request_queue add a list_head of "interested drivers"
- In a dm map, add:
struct interested_driver {
list_head list;
void (*plug_upcall)(struct request_queue *q, void *private);
void (*unplug_upcall)(struct request_queue *q, void *private);
void *private;
}
and when setting up a map, dm does:
blk_register_interested_driver(struct request_queue *q,
struct interested_driver *d)
{
list_add(&d->list, q->interested_driver_list);
}
- In blk_device_plug():
list_for_each_entry(d, q->interested_driver_list, list) {
(*d->plug_upcall)(q, d->private);
}
- Similar in the unplug functions.
And in dm, maintain a dynamically allocated array of request_queue*'s:
dm_plug_upcall(struct request_queue *q, void *private)
{
map = private;
map->plugged_queues[map->nr_plugged_queues++] = q;
}
dm_unplug_upcall(struct request_queue *q, void *private)
{
map = private;
for (i = 0; i < map->nr_plugged_queues; i++) {
if (map->plugged_queues[i] == q) {
memcpy(&map->plugged_queues[i],
&map->plugged_queues[i+1],
<whatever>
}
}
}
unplug_upcall is a bit sucky, but they're much less frequent than the
current unplug downcalls.
Frankly, I wouldn't bother. 0.5% CPU when hammering the crap out of a
56-disk LVM isn't too bad. I'd suggest you first try to simply reduce the
number of cache misses in the inner loop, see what that leaves us with.

I don't follow at all. If dm initiates io against /dev/hda2, it's part
of that mapped device and it can trigger and note the unplug just fine.
If io goes through a 2nd level of dm maps that isn't an issue either,
the 2nd level dm device will maintain the state needed to unplug that
device automagically.
But it does get a bit hairy, and I'm getting lost in dm data
structures...

I guess that'd work ok, as far as I can see..

Yeah I guess you are right, probably not a worry. At least not now, and
the dm folks can always play with the above if they want.
I'll send you a small update for -mm with the unconditional unplug
killed (at least it cuts it in half) and analyzed the loop.

Right. But suppose I have a plain old ext2 fs mounted on /dev/hda1. I do
some I/O against /dev/hda1, and that causes the /dev/hda queue to be
plugged. Device mapper doesn't know that the queue is currently plugged,
because it was some totally unrelated piece of code which caused the plug.

You are right, that breaks. No good.

I implemented exactly this for the congestion stuff. It
isn't perfect, but perhaps it is of some use:

It got shot down because it was too complicated..

It is, at least the profiles so far don't even warrant it. It's worth to
keep in mind, though.

Thanks, so it's the CPU scheduler changes. Is that machine hyperthreaded?
And do you have CONFIG_X86_HT enabled?

Yes and CONFIG_X86_HT is enabled but I have hyperthreading disabled with
'acpi=off noht' (whichever one does it.)

The oprofile for the 01 kernel says
CPU: P4 / Xeon, speed 1497.76 MHz (estimated)
while the 02 kernel says
CPU: P4 / Xeon with 2 hyper-threads, speed 1497.57 MHz (estimated)
What's going on there?
Other than that, nothing in the kernel profile jumps out at me:
schedule, __copy_from_user_ll and __copy_to_user_ll are all
significantly lower *after* the CPU scheduler changes, which
is an indicator that cache behaviour is better.
Sar says average context switches/second were 9064 and 6567 before
and after.
The only thing I can see is the CPU utilisation averages show the
scheduler patches have more of a tendancy to load up one CPU more
before moving to another. This actually should be good behaviour,
generally but I wonder if it is hurting at all. I would be really
surprised if it was that significant.

CONFIG_X86_HT=y does not enable HT.
CONFIG_X86_HT=n does not disable HT.
It only controls if the cpu_sibling_map[] etc. are initialized.
acpi=off does not disable HT
"noht" doesn't exist.
Please see my message yesterday w/ subject "how to disable HT"

Does the sched-domains patch break `acpi=off' or `noht'?

No, it indicates that the kernel is getting less work done.

This machine is I/O-bound, the CPUs are mostly idle. It would appear to be
some interaction between the I/O system and the CPU scheduler. Haven't we
seen that with reaim also?

Err, the question I meant to ask Mark was "do you have CONFIG_SCHED_SMT
enabled?"

If you are measuring the same period of time, yes. If you
are measuring the same amount of work, no. I assumed the
latter. Maybe I'm wrong.

I can't remember how much CPU reaim uses, I thought it was
quite a lot (ie. not IO bound).

oops, that line incorrect.
we fixed "acpi=off" to _really_ mean ACPI off -- table parsing
and all, so it does disable HT, along w/ all the other stuff
that depends on ACPI.

CONFIG_SCHED_SMT isn't set. :)

So how come oprofile seems to think there is a sibling?
Can you verify both cases use physical only CPUs?

aim / reaim supports multiple different workloads (including custom ones) -
whether it's IO bound or CPU bound depends on which you pick.

I think that one made it into rc2. It breaks uml compilation,
CC kernel/acct.o
IKCFG kernel/ikconfig.h
GZIP kernel/config_data.gz
IKCFG kernel/config_data.h

There is a missing dependency on 'scripts' in the Makefile.
Try add scripts as target on the line that says something like:
$(SUBDIRS): prepare-all scripts
^---- The scripts target you shall add.
$(Q)$(MAKE) $(build)=$@
Cannot test rigth now - not on my Linux machine.

This patch is needed to fix the compile. Odd, make -jN works.

That seems like a lot of pages for a small race, it feels like we have a
bigger problem. If nobody else has ideas, and you've got an available
disk for mkreiserfs, could I talk you into trying with reiserfs
data=ordered?
ftp.suse.com/pub/people/mason/patches/data-logging/experimental/2.6.4
(use series.mm for a list of files to apply to 2.6.5-rc-mm)
data=ordered is the default with those patches, so just mkreiserfs and
mount. reiserfs is using a different writepage and different code to
submit the ordered buffers, so you'll be using completely different code
paths.
I'll try to get some time on an 8way here for some tests as well.

The sar output still only lists data for 4 individual CPUs. Is that a
good way to verify it?
[was "Poor DBT-3 pgsql 8way numbers on recent 2.6 mm kernels" on
linux-mm]
Andrew,
This same patch (02) applied in STP (plm 2780) when run against
dbt3-pgsql DSS workload displays the performance problem with the
throughput numbers that I reported on linux-mm on our 8way systems,
where the previous patch (plm 2777 -01) does not.
Here is the data (patches applied to 2.6.5-rc1)
PLM.....CPUs.Runid..Thruput Metric (bigger is better)

2779(02) 8 290304 88.57 (-35.9%)
The 8way is a 700MHz (1024k processor cache) with 8GB of memory.

Andrew and Chris,
I re-ran the direct_read_under tests over the weekend on ext3 with
the attached wb_rwsema patch and ran without errors.
It looks like the same thing as before -- async writebacks are causing
the sync writebacks to miss pages.
Thoughts?

It does seem clear that's what is happening, but the part I don't

Wait, maybe I do see it.
In __block_write_full_page, if the buffers are locked by ll_rw_block and
under io, they are clean. The page is only redirtied in this case
because the buffers are clean.
So we set_page_writeback and nr_underway == 0. Then, in the if
(nr_underway == 0) code, we clear page writeback even though the buffers
are still locked and under io.

This hunk alone should be enough to force the sync writers to find a
page with locked but clean buffers.

I was thinking about this also, since this is included in the patch.
As long as the page stays dirty in radix tree so the sync writer
can find it, then the sync writer can wait on the locked buffers.
I am giving it a try and will let you know.

Please do.
Redirtyng the pages in this manner does mean that background_writeout()
could get stuck in a loop trying to write the same batch of pages over and
over again, until the I/O completes.
I'll take another look at marking the pages which back the ll_rw_blk
buffers as being under writeback.

36% regression due to the CPU scheduler changes? ow.
And that machine is a PIII, so presumably the setting of CONFIG_SCHED_SMT
makes no difference.

Andrew,
The test has been running over 5 hours now without seeing uninitialized
data. I'll let it run overnight, but it looks like the small
__block_write_full_page patch fixes the problem.

OK, thanks. It does cause gargantuan amounts of CPU consumption as
expected. The below version fixes that up. I'm not 100% happy with it,
but it seems OK on the profiles.

Andrew,
Just to confirm my tests ran overnight without errors.
So the !wbc->nonblocking lowers the cpu utilization.
What does sync_mode=WB_SYNC_ALL and nonblocking=1 mean?

good.

yup. It prevents balance_dirty_pages() callers from spinning over the same
pages again and again.
> What does sync_mode=WB_SYNC_ALL and nonblocking=1 mean?
WB_SYNC_ALL means "we're performing this writeout for data-integrity
purposes, as opposed to for a regular dirty memory flush". The code paths
for these two things are deep, and are almost identical, so we pass it up
and down in a flag.
->nonblocking means "try to avoid blocking on request queues or locked
pages". pdflush and kswapd set this because those processes must serve
many queues and cannot accord to get stuck on any one queue. But regular
write() callers do not set ->nonblocking because we _want_ these guys to
throttle.
It's only OK to let pdflush avoid blocking on the buffer because pdflush
will take an explicit nap in background_writeout(). hm, but only if the
queue is congested - we may still have a problem there.

I'm not sure why you think this is IO bound. For
the throughput phase of the test (from which the
metric above is taken) there is very little physical
IO except at the start when the updates occur. They
finish in a few minutes, after which there is very
little.
http://khack.osdl.org/stp/290304/results/plot/thuput.vmstat_io.png
http://khack.osdl.org/stp/290304/results/plot/thuput.vmstat.txt
Perhaps you were looking at the start or at some other
part of the test?
The power test (single stream phase) does not display
any performance hit at all compared to the baseline.
The throughput test runs eight streams (processes)
and does display the problem. Furthermore the problem
is worse on 8 ways than on 4 ways. It seems reasonable
to me that this could be due to a task schedule issue.
Am I missing something?

There seems to be a large amount of idle time in the profiles and in the
vmstat trace.
It looks like every place wbc->nonblocking is set to 1, sync_mode
is set to WB_SYNC_NONE, but there are places where WB_SYNC_NONE is
used and nonblocking is NOT set:
balance_dirty_pages()
try_to_unuse()
So your patch makes balance_dirty_pages() do the lock_buffer()
in __block_write_full_page() instead of skipping and redirtying
the page.
I just making sure I understand.
So, WB_SYNC_ALL and nonblocking=1 should never be used?

Correct, setting both WB_SYNC_ALL and nonblocking=1 doesn't make sense.

Yes. There is considerably more idle time in the bad run:
Good one:

Bad one:
http://khack.osdl.org/stp/290304/results/plot/thuput.sar_cpu_all.png
I am concerned with the drop in CPU utilization relative to
the other run.
