| Serge E. Hallyn | [PATCH] cgroup_clone: use pid of newly created task for new ...
cgroup_clone creates a new cgroup with the pid of the task. This works
correctly for unshare, but for clone cgroup_clone is called from
copy_namespaces inside copy_process, which happens before the new pid
is created. As a result, the new cgroup was created with current's pid.
This patch:
1. Moves the call inside copy_process to after the new pid
is created
2. Passes the struct pid into ns_cgroup_clone (as it is not
yet attached to the task)
3. Passes a name from ns_cgroup_clone() in...

From: Alexey Kuznetsov <kuznet@ms2.inr.ac.ru>
Yes, we discussed the locking issue over past few days. See
the thread: "stuck localhost TCP connections, v2.6.26-rc3+"
More and more, the arguments are mounting to completely revert the
established code path changes, and frankly that is likely what I am
going to do by the end of today.

There are a couple of blocked on type structures. One for mutexes, and one
for rtmutexes, and we also need one for futexes.
Instead of just adding another one to the task struct I combined them all into
a union. Since a waiter can only be blocked on one of the types at any given
time this should be safe.
I also usurped the pi_lock as the lock which protects all the blocked_on types.

sysvipc_shm_proc_show() picks between format strings (based on the

gcc from performing format checks on the seq_printf() parameters. This
hid two format errors - shp->shm_segsz and shp->shm_nattach are both
unsigned long, but were being printed as unsigned int and signed int
respectively. This leads to 32-bit truncation of SHM segment sizes

I'm probably missing something fundamental--why doesn't

Someone's seeing a performance problem with the linux nfs server. One
of the symptoms is the "size-4096" slab cache seems to be out of
control. I assumed that meant that memory allocated by kmalloc() might
be leaking, so figured it might be interesting to turn on

Ah, I missed that! I'm a little confused as to how those flags behavior
affect the collection of the leak debugging data, but I can verify that
the below does result in size-4096 showing up in /proc/slab_allocators;
hopefully there's no more negative result than the performance penalty.
Norman, do you think you could try applying this and then trying again?

Make sure that mlocked pages also live on the unevictable

This is achieved through various strategies:
1) add yet another page flag--PG_mlocked--to indicate that
the page is locked for efficient testing in vmscan and,
optionally, fault path. This allows early culling of
unevictable pages, preventing them from getting to

| Rik van Riel | [PATCH -mm 20/24] swap: cull unevictable pages in fault path
From: Lee Schermerhorn <lee.schermerhorn@hp.com>
In the fault paths that install new anonymous pages, check whether
the page is evictable or not using lru_cache_add_active_or_unevictable().
If the page is evictable, just add it to the active lru list [via
the pagevec cache], else add it to the unevictable list.
This "proactive" culling in the fault path mimics the handling of
mlocked pages in Nick Piggin's series to keep mlocked pages off
the lru lists.
Notes:
1) This patch is optio...

| Rik van Riel | [PATCH -mm 23/24] mlock: count attempts to free mlocked page
From: Lee Schermerhorn <lee.schermerhorn@hp.com>
Allow free of mlock()ed pages. This shouldn't happen, but during
developement, it occasionally did.
This patch allows us to survive that condition, while keeping the
statistics and events correct for debug.

I changed that to CONFIG_UNEVICTABLE_LRU.
Did we agree that the presence of this config variable is undesirable?
If so, what's involved in making it go away?

I noticed that the vmstat items [perhaps these will go away] still use
Not sure we did. It does add quite a bit of code that probably wouldn't
be needed/wanted for, say, a laptop system or other small systems that
still have an mmu. I initially made it configurable keeping in mind
your speeches about not burdening smaller systems with larger system
Just some busy work. I added a fair number of wrappers and such to
minimize #ifdefs in the .c files. This resulted in quite a few such

Do you have patch 21/24 applied? In 26-rc5-mm1, I see the
noreclaim_pgs_* vmstat items. They're in the patch 21 you just posted,
as well.
Again, we might decide to drop that patch from the merge. I found the
stats useful during debug and test, but I don't know that they provide
any value in the longer term.

Doh!
I am working against:

You may want to send Andrew an update against patch 21/24 that
That's an option too. I'll let you and Kosaki-san decide on
that, since I had relatively little involvement with the
second half of the patch series recently.

We agreed that having CONFIG_NORELAIM_SWAP was bad, that one went away.
As for CONFIG_UNEVICTABLE_LRU, I believe we will want to at least give
embedded people the option to compile without all that code, similar
to CONFIG_SWAP.
