Ah, of course, it's commit 21ec12364bb78b72ad36b94269c64b3ee31b038f
(workqueue: remove noop condition check in worker_clr_flags()).  The
condition it removes is not a noop.  Reverting it.

Thank you.

Hey all

It looks that WORKER_NOT_RUNNING could be defined finer :/

It's an enum definition.  How does wrapping it inside () make it any
finer?

Thanks for the report. It's already fixed and I posted this a few days
ago to linux-mm.

I had to rewrite the KVM THP support when merging THP in -mm, because
the kvm code in -mm has async page faults and doing so I eliminated
one gfn_to_page lookup for each kvm secondary mmu page fault. But
first new attempt wasn't entirely successful ;), the below incremental
fix should work. Please test it and let me know if any trouble is
left.

Also note again on linux-mm I posted two more patches, I recommend to
apply the other two as well. The second adds KSM THP support, the
third cleanup some code but I like to have it tested.

Thanks a lot,
Andrea

====
Subject: thp: fix for KVM THP support

From: Andrea Arcangeli <aarcange@redhat.com>

There were several bugs: dirty_bitmap ignored (migration shutoff largepages),
has_wrprotect_page(directory_level) ignored, refcount taken on tail page and
refcount released on pfn head page post-adjustment (now it's being transferred
during the adjustment, that's where KSM over THP tripped inside
split_huge_page, the rest I found it by code review).

Yup, this works for me. If you point me to the other 2, I will test them
too...

Sure, and they're already included in -mm.

http://marc.info/?l=linux-mm&m=129442647907831&q=raw
http://marc.info/?l=linux-mm&m=129442718808733&q=raw
http://marc.info/?l=linux-mm&m=129442733108913&q=raw

I also included in aa.git the other fixes for migrate deadlocks
(anon_vma huge non-huge probably only reproducible with preempt but
theoretically not only preempt issues, lock_page readahead with slub,
and ksm-lru-drain accounting fix for one ltp ksm testcase) if you want
to test that too (they're in -mm as well of course).

Thanks,
Andrea

bnx2 card cannot be detected (WAS Re: mmotm 2011-01-06-15-41 uploaded)

[CAI Qian]

After updated to this kernel, my system with bnx2 card (Ethernet controller: Broadcom Corporation NetXtreme II BCM5709S Gigabit Ethernet (rev 20) can't be detected. The system has no any of eth*. mmotm 2010-12-02-16-34 version is working fine there. Is this a known issue?

Hi, after some uptime and several suspend/resume cycles, I got:

I changed those BUG_ONs to WARN_ONs intentionally because I had problems
with that previously -- I had to:
dentry->d_flags &= ~(DCACHE_OP_HASH | DCACHE_OP_COMPARE |
      DCACHE_OP_REVALIDATE | DCACHE_OP_REVALIDATE_RCU |
      DCACHE_OP_DELETE);

in d_set_d_op to not oops when calling NULLish op->d_delete later.


The "Tainted: G        W" is caused by:
https://lkml.org/lkml/2011/1/10/63

So DCACHE_OP_REVALIDATE remained set.

Thanks for reporting. I was a little over-optimistic in my assumption
that filesysystems
would be doing sane things with dentry->d_op.

Al has audited these guys and has a pull request pending.

In the meantime, avoiding the bug and flipping the bits off will work fine.

Thanks,
Nick

Wow. So it wasn't just configfs that trips over this one.  I'm now hoping that
Al audited all the pseudo file systems for this...

Well, CCing Al.

I don't see any recent change in fs/autofs4 in:
http://git.kernel.org/?p=linux/kernel/git/viro/vfs-2.6.git;a=history;f=fs/autofs4;hb=refs/heads/for-next

So maybe not all?

Did you see:

Haven't had any feedback on this yet, odd or maybe no news is good news?
