I thought this one was closed with the revert of the slot symlink?

Yup, this is still a regression. The fix is trivial (see below).

Not sure if this is a new bug or not...
I don't think this is really a CIFS bug, per-se. It seems like the
problem may be that the iterator for /proc/pid/mountinfo is not
sufficiently protected against removal from the vfsmount list.
Filesystems don't seem to be expected to do any locking in their
show_options routines though so I'm guessing that something is borked
in the generic vfs layer.
Either that or this is some sort of generic mem corruption? I'm open to
input from others that have a better grasp of this stuff at the VFS
layer...

Can be put down to bad ramdisk settings > actual memory, its probably
not a regression.
I think it can be closed for now, i'll do some testing and see if
ramdisk should complain before letting such configuration go through.

It might not be a regression, and so far i haven't been able to reproduce.
Its seems to be related to suspend/resume interface up/down and mount/unmount.
Also potentially with cifs waiting for a NAS to spinup to complete mount.

This is a gcc-4.5 issue. Whether it's also something that we should
change in the kernel is unclear, but at least as of now, the rule is
that you cannot compile the kernel with gcc-4.5. No idea whether the
compiler is just entirely broken, or whether it's just that it
triggers something iffy by being overly clever.

I'm not entirely sure if these RCU proving things should count as regressions.
Sure, the option to enable RCU proving is new, but the things it
reports about generally are not new - and they are usually not even
bugs in the sense that they necessarily cause any real problems.
That particular one is in the single-thread optimizated case for fget_light, ie
if (likely((atomic_read(&files->count) == 1))) {
file = fcheck_files(files, fd);
where I think it should be entirely safe in all ways without any
locking. So I think it's a false positive too.

Frederic? Al? I assume this is some late fallout from the BKL removal
ages ago.. It's the old filldir-vs-mmap crud, but normally it should
be impossible to trigger because the inode for a directory should
never be mmap'able, so we should never have the same i_mutex lock used
for both mmap and for filldir protection.
We saw some of that oddity long ago, I wonder if it's lockdep being
confused about some inodes.

This either got fixed, or will be practically impossible to debug. The
reporter ends up being unable to reproduce the issue.

This seems to be due to CONFIG_MRST (Moorestown).

This seems to be partly a confusion about what "load average" is. It's
not a CPU load, it's a system load average, and disk-wait processes
count towards it. He has some problem with his CD-ROM, and it sounds
like it might be hardware on the verge of going bad.

I wonder if this is the writeback problem. That POWER crash dump is
unreadable, so it's hard to tell, but the load in question makes that
at least likely.
If so, it should hopefully be fixed in today's git (commit
83ba7b071f30f7c01f72518ad72d5cd203c27502 and friends).

See earlier about these being marked as regressions, but it should be
fixed by commit dc61b1d6 ("sched: Fix PROVE_RCU vs cpu_cgroup").

Ok, this is definitely harmless. Whether we should silence the warning

This has a butt-ugly suggested patch that certainly won't be applied.

some resolution?

These should all be gone. See commit 3be434f0244ee by Jesse ('Revert
"PCI: create function symlinks in /sys/bus/pci/slots/N/"').

David? This bisects to a networking commit. Doesn't look sensible, but

Hmm. That one is the vt.c bug coupled with another problem, which in
turn got opened as a separate bugzilla entry:
http://bugzilla.kernel.org/show_bug.cgi?id=16252
which in turn then got closed. I dunno.

Not a regression or a kernel bug at all. See the thread. Big ramdisk
filled up all of memory when it was filled by the builds.

This is not a regression. See the full bugzilla details. The same
problem persists at least back to 2.6.30 with his config. So it's
somehow specific to his particular config use that requires "notsc" to
boot.

This looks like a duplicate of that 16312 bugzilla entry. Jens, has
this been resolved?

Right. In fact it wasn't a regression. The per task breakpoint reservation
design was broken from the beginning and this warning has revealed the
problem. This only touched perf, and it did since perf support breakpoints.
Fortunately ptrace wasn't concerned by this problem, even not by side effects
of this.
The fix is invasive as it's a rewrite of a (little) part of the breakpoint
reservation. And since the symptom is only a warning and also breakpoints
never released from the constraint table (just a counter, no memory leak),
the fix is headed for 2.6.36.
It is ready in tip:/perf/core:
http://git.kernel.org/?p=linux/kernel/git/tip/linux-2.6-tip.git;a=commitdiff;h=45a73372efe4a63f44aa2e1125d4a777c2fdc8d8
I think this ticket can be safely closed.
Thanks.

I think it has been there from the beginning. At least it was there before
the reiserfs bkl removal in .32.
Indeed the readdir <-> unmap/release inversion problem can not happen.
But Al said that can happen between write and release. (Although I don't see
where write takes the inode mutex).
He also highlighted the fact that reiserfs refcounting based on i_count
was totally broken.
He has a fix the whole in the vfs tree, in the for-next branch on commit
6c2bdaf089a3876226893fab00dd83596c465ad2
"Fix reiserfs_file_release()"
No more uses of the i_mutex on release after that, nor i_count, but a private
openers refcount and a tailpack mutex per reiserfs inode.

Continues with July 7th, snapshot of 2.6.35-rc4.
Some more info: I have USB in use while trying to suspend. A USB Microsoft
Mouse and a QuickCam Pro 9000 camera connected.

My suspicion is that dhcpd uses netlink to dump the info of the
available links, and due to some bug gets confused with the new 64-bit
statistic netlink attribute being there now.
That shouldn't happen, applications should just ignore the attributes
which they don't understand.
I'll try to find a second to have a look at this.

It could be a dhcpcd bug because of extended size of answer
According to strace, dhcpcd tries a recvmsg() call with
a 256 bytes buffer to hold answer.
Looking at current dhcpcd source, I confirm it cannot realloc its buffer
static int
get_netlink(int fd, int flags,
int (*callback)(struct nlmsghdr *))
{
char *buffer = NULL;
ssize_t bytes;
struct nlmsghdr *nlm;
int r = -1;
buffer = xzalloc(sizeof(char) * BUFFERLEN);
for (;;) {
bytes = recv(fd, buffer, BUFFERLEN, flags);
if (bytes == -1) {
if (errno == EAGAIN) {
r = 0;
goto eexit;
}
if (errno == EINTR)
continue;
goto eexit;
}
This program needs to fix this.

Agreed, I don't there is any reasonable way we could cater to this
application bug with some compatability bits. Restricting the link
dump to 256 bytes is just too much inflexibility.
If NetworkManager can get this right, dhcpd very well can too :-)

Seems like the patch didn't make it into mainline yet. So I guess it should
still be listed here.

Generally not - and we've delayed at least one more complex (cgroups) fix to
v2.6.36 because the patch itself was riskier than the warning.
Still most of the warning fixes turned out to be simple, so we merged the
very-low-risk ones and right now we seem to be on top of them.
But in general the default rule is that we delay these fixes to v2.6.36.

Yeah, it's a bit like with lockdep (and it's a bit like with compiler warning
fixes): we had to punch through a large stack of false positives that
accumulated in the past 10 years.
( Because real bugs eventually get fixed, while false positives always just
accumulate. So almost by definition we always start with a very assymetric
collection of warnings and a large stack of false positives. )
Having said that, it appears we got most of the false positives and are
beginning to be in a more representative equilibrium now. If v2.6.35 isnt
going to be warning-free then v2.6.36 certainly will be and new warnings will
have a much higher likelyhood of being real (and new) bugs (not just
accumulated false-positives).

Yeah, this is weird. Norbert, do you still see this? Have you tried

Well... Let me try; being the firts time I send a bug report I've just
to learn how to do this kind of stuff. In this moment I'm compiling -rc4
to see if the "problem" persists. After, I'll try to go on with bisecting.

I wrote in my last comment of this bug that in *most* of the cases
the
echo "mem" > /sys/power/state
works perfectly, and I'm using it permanently now.
The problem seems to be in combination with some pm-utils scripts.
I still haven't been able to pin-point the actual pm-utils script that
causes the problem, since that is something not 100% reproducible.
Futhermore, *once* (only once!) the echo mem > method failed as written in
the bug report with :
[16273.....] PM: resume of devices complete after 2115.046 msecs
[16273.....] Restarting tasks ... done
[16273.....] video LNXVIDEO:00: Restoring backlight state
hanging here, but only once, not any time again.
It is hard to say what the culprit is, some new pm-utils script maybe,
since it happens even when I switch pm-utils to use the kernel method
(echo mem) to suspend, and not uswsusp (s2ram prog).
I would suggest keeping that bug closed until I have found the pm-utils
or a specific culprit, then I can reopen it or open a new bug.
(more disturbing are iwlagn bugs, they are a PITA without any progress)

This continues even with no USB devices plugged in. Will try with today's
snapshot build from Linus's tree. If this still happens, I'll see about
bisecting.
Thanks,

I also am testing this patch I noticed in anholt's tree, this may be GPU
suspend issue.

Made no difference, today's git snapshot, 2.6.35-rc5-git4 w/ airlied + anholt
drm git trees still hangs attempting to suspend. in Fedora, it drops to the
Fedora logo w/ KMS mode then fails to finish suspending (moon light flashes
off and on), I do hear the disk heads parking though.
I will look at bisecting this week when time permits. If anyone else might
know what might be the issue it would save some time in the bisecting.
Thanks,
Shawn.

Well, nothing comes to mind immediately at the moment.
