Subject: [PATCH] pagemap: add page-types tool, fix build
Latest -git fails to build:
make[2]: *** No rule to make target `Documentation/vm/slqbinfo.c',
needed by `Documentation/vm/slqbinfo'. Stop.
but slqbinfo.c is not yet upstream. Fix the makefile.

a new warning started popping up today, in the new page allocator
code. The allocation came from kmemleak:

This is not my changes as such. As part of another discussion, a warning
was added for high-order __GFP_NOFAIL allocations. The changelog for
commit dab48dab37d2770824420d1e01730a107fade1aa [page-allocator: warn if
__GFP_NOFAIL is used for a large allocation] has more details.

No super sure who is responsible here but could you check
/proc/slabinfo. Is cfq_queue now requiring high-order allocations for
its slabs?

Kmemleak needs to allocate memory for the pointer tracing and it
currently passes the same gfp flags as those used by the original
caller. In this case cfq_find_alloc_queue uses __GFP_NOFAIL.
The reason for this was to avoid GFP_ATOMIC if the caller wasn't
requiring it. I think the approach below is better:

Patch as follows
==== CUT HERE ====
profile: Suppress warning about large allocations when profile=1 is specified
When profile= is used, a large buffer is allocated early at boot. This can
be larger than what the page allocator can provide but the caller is able
to handle the situation. A warning is printed when too large an order is
given to the page allocator to indicate the caller might need fixing up
but the caller in this case is all right already. The warning looks
something like
[ 0.000007] ------------[ cut here ]------------

This patch suppresses the warning for profile= when the order is too
high for the page allocator to satisfy.

How about defining a GFP_SLAB_KMEMLEAK_MASK the subset of flags that kmemleak
should use? Based on this patch, the following appears to be it's definition.

Do you mean defining one in the gfp.h file? I think this would be better
placed in the kmemleak.c file as no other part of Linux would be using
it.
I personally find defining the GFP_KMEMLEAK_MASK as (GFP_KERNEL |
GFP_ATOMIC) more readable than using the individual bits since this
states clearly what type of allocations would be allowed (and safer if
someone later decides to improve the GFP_KERNEL or GFP_ATOMIC
definitions).

Yes, I meant placing it in the gfp.h file but I don't feel super strongly
about it. Defining it in kmemleak.c is fine too and is easier to read than
placing the mask directly at the call site.

That's fair enough.

Kmemleak allocates memory for pointer tracking and it tries to avoid
using GFP_ATOMIC if the caller doesn't require it. However other gfp
flags may be passed by the caller which aren't required by kmemleak.
This patch filters the gfp flags so that only GFP_KERNEL | GFP_ATOMIC
are used.

Is this really safe? What if we're in a middle of a filesystem
operation that uses GFP_NOFAIL and all of a sudden kmemleak allocation
fails and causes a panic?

A kmemleak_panic() call only disables the kmemleak but doesn't stop the
kernel. The __GFP_NOFAIL allocation had already happened and the pointer
returned to the caller.
If we pass the __GFP_NOFAIL flag via the kmemleak's alloc, we get the
warning reported by Ingo (though it's not clear to me why this happens
as a kmemleak_object cache allocation is 192 bytes on a 32 bit machine).
Are there (common) situations where we expect kmemleak's alloc to fail
without __GFP_NOFAIL?

Ah, ok. I was confused by the name of kmemleak_panic() (which could use
renaming methinks).

Right now it warns about any order but 0, and I think that's likely bogus.
It's fine to allow small orders (I'd suggest 0-2), since we should always
be able to get those, and small kmalloc's generally do want more than one
page just to avoid crazy fragmentation issues.
See, for example, the whole 'slab_break_gfp_order' logic in mm/slab.c: it
very much expects to be able to use order-1 allocations for kmalloc() if
there is enough memory (where "enough" is actually just 32MB). And slub
seems to put some limit at PAGE_ALLOC_COSTLY_ORDER (3).
So apart from anything else (ie this particular case is possibly fixable
in kmemleak), I do think that we should likely allow at least order-1 and
possible order-2 allocations with __GFP_NOFAIL too.

I saw about half a dozen of different warning patterns during the
day, so the warning definitely feels a bit over-eager.

Looks like there's a little typo up there, "Kkmemleak" should be
"kmemleak" no ?

It's sortof related in that it's another source of NOFAIL high-order

I have no idea why the stack trace is so badly managed but the problem appears
to be in DCCP so can you try the patch below please? It applies on top of the
profile=1 patch fix. If it works for you, I'll split out the patch properly
into three separate patches and repost.
Some questions though
1. Could DCCP use alloc_large_system_hash()?
2. Any idea why the stack trace for the warning was so useless?
==== CUT HERE ====
dccp: Suppress warning about large allocations from DCCP
The DCCP protocol tries to allocate some large hash tables during
initialisation using the largest size possible. The allocator warns if
the allocations are too large but the caller is able to handle
allocation failure. This patch disables the warnings in the case DCCP
requests too large an allocation.

This patch, on top of your "profile=1" fix and applied to -git17,
does indeed fix the problem for me.

Thanks for testing. I've posted a split-out set so this should get
ironed out over the next while.

Possibly. Ideally this should use whatever TCP is using now, as this
came more or less intact from there. IIRC it was not shared because TCP
used/uses alloc routines that were available only at boot time, DCCP
can't use it because it can be loaded as a module.
I'd say go with this patch and later, after FISL (this week) I'll look
at this again.
So, for the NOWARN bits:
