ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.26-rc5/2.6.26-rc5-mm2/

- This is a bugfixed version of 2.6.26-rc5-mm1 - mainly to repair a
  vmscan.c bug which would have prevented testing of the other vmscan.c
  bugs^Wchanges.


Boilerplate:

- See the `hot-fixes' directory for any important updates to this patchset.

- To fetch an -mm tree using git, use (for example)

  git-fetch git://git.kernel.org/pub/scm/linux/kernel/git/smurf/linux-trees.git tag v2.6.16-rc2-mm1
  git-checkout -b local-v2.6.16-rc2-mm1 v2.6.16-rc2-mm1

- -mm kernel commit activity can be reviewed by subscribing to the
  mm-commits mailing list.

        echo "subscribe mm-commits" | mail majordomo@vger.kernel.org

- If you hit a bug in -mm and it is not obvious which patch caused it, it is
  most valuable if you can perform a bisection search to identify which patch
  introduced the bug.  Instructions for this process are at

        http://www.zip.com.au/~akpm/linux/patches/stuff/bisecting-mm-trees.txt

  But beware that this process takes some time (around ten rebuilds and
  reboots), so consider reporting the bug first and if we cannot immediately
  identify the faulty patch, then perform the bisection search.

- When reporting bugs, please try to Cc: the relevant maintainer and mailing
  list on any email.

- When reporting bugs in this kernel via email, please also rewrite the
  email Subject: in some manner to reflect the nature of the bug.  Some
  developers filter by Subject: when looking for messages to read.

- Occasional snapshots of the -mm lineup are uploaded to
  ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/mm/ and are announced on
  the mm-commits list.  These probably are at least compilable.

- More-than-daily -mm snapshots may be found at
  http://userweb.kernel.org/~akpm/mmotm/.  These are almost certainly not
  compileable.

BTW. this is known to be broken with x86 1GB pages and direct-IO, due
to interaction between huge pages patchset and lockless get_user_pages.

My fault. I was away from the screen over the long weekend here, and
didn't give Andrew the heads-up in time.

This isn't going to be a problem unless you explicitly enable GB pages
and run direct IO (or splice) into or out of them. I can give a fixup
patch to anyone interested in doing so.

BTW. would be trying to test this more myself, but last mm I based the
lockless patches on didn't boot, and this one dies pretty quickly when
you try to get into reclaim:

The tmpfs PageSwapBacked stuff seems rather broken. For
them write_begin/write_end path, it is filemap.c, not shmem.c,
which allocates the page, so its no wonder it goes bug. Will
try to do more testing without shmem.

Also, just noticed
mm/memory.c:do_wp_page
//TODO:  is this safe?  do_anonymous_page() does it this way.

That's a bit disheartening. Surely a question like that has to
be answered definitively? (hopefully whatever is doing the
asking won't get merged until answered)

rikstuff.  Could be that the merge caused a problem?

It would be good if you could find a day to look through those changes
please.  It's pretty important.

Doesn't look like it, but I hadn't followed the changes too closely:
rather they just need to test loopback over tmpfs.

OK, I could have a look through them at some point.

Just something very quick while I have Rik's attention are all the
atomic SetPageSwapBacked bitops over a lot of mm/ fastpaths that I have
been slowly working away to get rid of over the past years. Maybe some
don't consider it a big deal, but a single one costs anywhere from
100 - 500 instructions on desktop CPUs, not including secondary effects
of ordering memory and and compiler barrier. Please go through and
ensure you know your page references and ->flags concurrency, and cut
these down to a bare minimum.

Is the plan to merge all reclaim changes in a big hit, rather than
slowly trickle in the different independent changes?

It's going to take a lot of work to get such extensive reclaim changes
landed.

We need to convince ourselves that these changes are the right way to
fix <whatever they fix>.  We need to review and test the crap out of
them.  The 64-bit-only thing is a concern.  I wonder about whether
we've "fixed" anon pages but didn't do anything about file-backed
mapped pages.  Plus all the other stuff, plus stuff we haven't thought
of yet.

It's huge.

Quite possible.  The reclaim policy for file-backed pages has not
changed.  We don't know yet whether we'll have to change that, too.

Does loopback over tmpfs use a different allocation path?

My original plan was to merge them incrementally, but Andrew is
right that we should give the whole set as much testing as
possible.

I have done all the cleanups Andrew asked and fixed the bugs
that I found after that merge/cleanup.  Your bug is the one
I still need to fix before giving Andrew a whole new set of
split LRU patches to merge.

(afterwards, I will go incremental fixes only - the cleanups
he asked for were just too big to do as incrementals)

I'm sorry, hmm I didn't look closely enough and forgot that
write_begin/write_end requires the callee to allocate the page
as well, and that Hugh had nicely unified most of that.

So maybe it's not that. It's pretty easy to hit I found with
ext2 mounted over loopback on a tmpfs file.

Turns out the loopback driver uses splice, which moves
the pages from one place to another.  This is why you
were seeing the problem with loopback, but not with
just a really big file on tmpfs.

I'm trying to make sense of all the splice code now
and will send fix as soon as I know how to fix this
problem in a nice way.

The loop-on-tmpfs write side is okay nowaways, but the read side
still has to use shmem_readpage, with page passed in from splice.

There's no need to make sense of all the splice code, it's just
that it's doing add_to_page_cache_lru (on a page not marked as
SwapBacked), then shmem and swap_state consistency relies on it
as having been marked as SwapBacked.  Normally, yes, shmem_getpage
is the one that allocates the page, but in this case it's already
been done outside, awkward (and long predates loop's use of splice).

It's remarkably hard to correct the LRU of a page once it's been
launched towards one.  Is it still on this cpu's pagevec?  Have we
been preempted and it's on another cpu's pagevec?  If it's reached
the LRU, has vmscan whisked it off for a moment, even though it's
PageLocked?  Until now it's been that the LRUs are self-correcting,
but these patches move away from that.

I don't know how to fix this problem in a nice way.  For the moment,
to proceed with testing, I'm using the hack below.  But perhaps that
screws things up for the other !mapping_cap_account_dirty filesystems
e.g. ramfs, I just haven't tried them yet - nor shall in the next
couple of days.

It could be turned into a proper bdi check of its own, instead of
parasiting off cap_account_dirty.  But I'm not yet convinced by any
of the PageSwapBacked stuff, so currently preferring a quick hack
to a grand scheme.

It's not clear to me why tmpfs file pages should be counted as anon
pages rather than file pages; though it is clear that switching their
LRU midstream, when swizzled to swap, can have implementation problems.

I don't really get why SwapBacked is the important consideration:
I can see that you may want different balancing for pages mapped
into userspace from pages just cached in kernel; but SwapBacked?

Am I right to think that the memcontrol stuff is now all broken,
because memcontrol.c hasn't yet been converted to the more LRUs?
Certainly I'm now hanging when trying to run in a restricted memcg.

Unrelated fix to compiler warning and silly /proc/meminfo numbers
below too, that one raises fewer questions!

Yeah, it will break ramfs.  Also, we need to take care of
splice going in the opposite direction (moving a page from
SwapBacked to filesystem backed).

I guess we'll need per-mapping flags to help determine where
a page goes at add_to_page_cache_lru() time.

This does not remove our need for the page flags, because
those need to survive until the del_page_from_lru() call
in __page_cache_release(), by which time the page->mapping
will be long gone.

I believe memcontrol has been converted.  Of course, maybe
they changed some stuff under me that I didn't notice :(

I sent the fix for that one to Andrew already.  I believe
it's in his mmotm tree.

No, that's a different, and blessedly non-existent, problem.

The swap_state.c:77s we're seeing with loop-on-tmpfs-file just comes
from __generic_file_splice_read doing add_to_page_cache_lru without
knowing that the filesystem it's dealing with is tmpfs, which unlike
every other filesystem sets and expects PageSwapBacked on its pages.
(I expect you started out without that, then hit problems when tmpfs
moved its file pages to swap cache, so you therefore elected to make
them SwapBacked from the start.)

You could certainly argue that tmpfs should therefore have its own
shmem_file_splice_read instead of using generic_file_splice_read;
but I'd rather hate to duplicate that splice code within shmem.c just
for this reason, would prefer that __generic_file_splice_read deduce it's
dealing with tmpfs and SetPageSwapBacked before add_to_page_cache_lru
(probably better that way than within add_to_page_cache_lru as I did).

Though I'd even more prefer to find a way of avoiding it altogether:
I've yet to think through on that.

But this is hardly a splice problem, it's just that splice is the
only thing which ever goes the problematic shmem_readpage route.

When above you say that we also need to take care of going the
opposite direction, you're thinking about splice stealing pages
from one mapping and giving them to another, the essence of splice.
But see Nick's year-old 485ddb4b9741bafb70b22e5c1f9b4f37dc3e85bd
"splice: dont steal" patch: that stealing is currently dead code,
so you shouldn't spend time worrying about how to deal with it.
Though we've all forgotten to either remove or correct that code.

> I guess we'll need per-mapping flags to help determine where

The better way would be to add a backing_dev_info flag.  (At one
point I had been going to criticize your per-mapping AS_UNEVICTABLE,
to say that one should be a backing_dev_info flag; but no, you're
right, you've the SHM_LOCK case where it has to be per-mapping.)

Ah, yes, there are NR_LRU_LISTS arrays in there now, so it has
the appearance of having been converted.  Fine, then it's worth
my looking into why it isn't actually working as intended.

I believe that Lee and Kosaki-san have tested this code,
so the breakage could be pretty new.

I put those C++ TODO comments in there specifically to raise their
visibility in hopes that someone [like you :)] would notice and maybe
have an answer to the question.  I noted the issue in the change log as
well--i.e., that I had moved set_pte_at() to after the lru_cache_add and
'new_rmap.   The existing order may be that way for a reason, but it's
not clear [to me] what that reason is.  As I noted, do_anonymous_page()
sets the pte after the lru_add and new_rmap.

I agree, these questions need to be answered and the TODO's resolved
before merging.   Any thoughts as to the ordering?

The ordering of lru_cache_add*, page_add_*_rmap and set_pte_at does
not matter (but update_mmu_cache must come after set_pte_at not before).

Even if the page table lock were not held across them (it is), I think
their ordering would not matter much (just benign races); though it's
always worth keeping in mind that once you've done the lru_cache_add,
that page is now visible to vmscan.c.

But I'm all in favour of you imposing consistency there (as part of
a wider patch? perhaps not; and do_swap_page does now look out of step).
It can sometimes help when inserting debug checks e.g. on page_mapcount.

I think you'll find the lru_cache_add_active_or_noreclaim could
actually be moved into page_add_new_rmap - I found that helpful when
working on eliminating the PageSwapCache flag (work now grown out of
date, I'm afraid), to know that the page was not publicly visible
until I did lru_cache_add_active at the end of page_add_new_rmap.

No it's not :)

-mm1 worked fine here but -mm2 locks up just after saying:
agpgart: Detected 7164K stolen memory.

Nothing in logs (session not recorded - hit reset to restart).

config and dmseg for -mm1 at (same .config for mm2):

hm, intel-agp gtt stuff.

Can you please see whether reverting Keith's stuff fixes it?

Interesting to try out, but I got this:

  $ make
   CHK     include/linux/version.h
   CHK     include/linux/utsrelease.h
   CALL    scripts/checksyscalls.sh

make[1]: *** [mm/vmscan.o] Error 1

I then tried to configure with "Track page owner", but that did not 
change anything.

Seems like you've got little or no anon pages left, so 1GB free swap
is no problem (nothing left to page out).

I would hope it is not a memory leak (which might point to lockless
pagecache). It doesn't look like it because there is still lots of
inactive file pages, so that points to the page reclaim changes
(which is not to say page reclaim changes couldn't cause a memory
leak themselves).

Curious: if you kill off all the LTP tests after the OOM condition,
what does your /proc/meminfo look like before and after running
sync ; echo 3 > /proc/sys/vm/drop_caches

Hey, I'm liking this kernel-testers list, btw. Makes it much easier
to help people with problems.

Luckily I suggested it at last KS. Oh wait, I recall everybody
laughed or ignored :) I guess I lack the managerial qualities to
make those kinds of suggestions!

Thanks for testing.  Again.

Well I assume that Rik ran LTP.  Perhaps a merge problem.

OK, weird.

Zero pages on active_anon and inactive_anon.  I suspect we lost those pages.

And what's up with the all_unreclaimable logic?  If that isn't working
then we'll spend lots of CPU scanning zones which aren't releasing any
pages.  Hopefully that won't be needed at all if all these patches work
as hoped, but I don't think Rik intentionally disabled it at this
stage.  But I've only read half his patches to date.

It is init that invokes the OOM killer, the actual process killed
comes at the end I believe:

at least, I ran LTP last week and its error didn't happend.
I'll investigate more.

Thanks.

FWIW, I can reproduce it reliably:
$ cd <ltp-dir>/testcases/bin
$ ./growfiles -W gf15 -b -e 1 -u -r 1-49600 -I r -u -i 0 -L 120 Lgfile1
And then wait for a few secs before the OOM triggers.

Regards,
Frederik

Known problem.  I fixed this one in the updates I sent you last night.

Oh good. Yeah I was just running some tests, and got as far as verifying
that the upstream kernel + lockless pagecache patches reclaims file pages
like a dream, but -mm2 sucks very badly at it.

During which, I also did find by inspection a little problem with my
speculative references patch. Andrew please apply this fix.


[-- Attachment #2: mm-speculative-page-references-hugh-fix3.patch --]
[-- Type: text/x-diff, Size: 1527 bytes --]

Fix the VM_BUG_ON assertion check to actually do what I want, noted by
Christoph.

Also, fix an error-path-leak type issue with frozen refcount not being
unfrozen. Found by review. In practice, this check is very rare to hit
because a page dirtier is likely to hold the refcount elevated for much
longer than it takes to check and non-racy-recheck. So it doesn't pose
a big problem for users of -mm, but of course needs fixing.

Hi Andrew,

The 2.6.26-rc5-mm2 kernel panic's, while booting up on the x86_64

Just to save everyone the trouble, it looks like this is a new BUG_ON().

Yes. Sorry, I already responded in a separate e-mail (see below), but
that obviously missed all the Ccs. So here it goes again...:

I'm betting

commit a953e4597abd51b74c99e0e3b7074532a60fd031
Author: Mike Travis <travis@sgi.com>
Date:   Mon May 12 21:21:12 2008 +0200

    sched: replace MAX_NUMNODES with nr_node_ids in kernel/sched.c

will fix this if it's not in -mm2 already.

The BUG() is simply there to prevent silent corruption. Mike already
has a patch that changes it to a WARN(), but it obviously didn't get
through (either)...
