Page tables can bite a relatively big chunk off system memory and their
allocations are easy to trigger from userspace, so they should be
accounted to kmemcg.
This patch marks page table allocations as __GFP_ACCOUNT for x86. Note
we must not charge allocations of kernel page tables, because they c

Without supporting clock PM capable, if we want to disable
clkpm, we don't need this extra check as it already be zero for
the enable argument. And it's the same for enabling clkpm here.
So let's remove this check.

Unix sockets can consume a significant amount of system memory, hence
they should be accounted to kmemcg.
Since unix socket buffers are always allocated from process context,
all we need to do to charge them to kmemcg is set __GFP_ACCOUNT in
sock->sk_allocation mask.

Patrice, can you rebase these two on top of Torvalds' fix and
resend?

debugfs_create_file_unsafe() is declared twice in exactly the same
manner each: once in fs/debugfs/internal.h and once in
include/linux/debugfs.h
All files that include the former also include the latter and thus,
the declaration in fs/debugfs/internal.h is superfluous.
Remove it.

This patch series fixes the following
1) fix might_sleep warning on socket shutdown:
Fix sock_shutdown to avoid calling kernel_sock_shutdown
while holding spin_lock.
2)fix various coding standard warnings
Make shutdown get called in a process context instead, using
system_wq.
3) make
spinlocked ranges should be small and not contain calls into huge
subfunctions. Fix my mistake and just get the pointer to the socket
instead of doing everything with spinlock held.

When a timeout occurs or a recv fails, then
instead of abruplty killing nbd block device
wait for it's users to finish.
This is more required when filesystem(s) like
ext2 or ext3 don't expect their buffer heads to
disappear while the filesystem is mounted.
Use a kref for users using this. The dev
If we get out of preempt_schedule_irq() then we check for NEED_RESCHED
and call the former function again if set because the preemption counter
has be zero at this point.
However the counter for lazy-preempt might not be zero therefore we have
to check the counter before looking at the need_resched
