I guess it is a good idea to batch these things. But can you
do that on all architectures? What happens if your tlb flush
happens after another thread already

Hi!
Fix the problem with kthread_stop() that causes the freezer to fail if a
freezable thread is attempting to stop a frozen one and that may cause the
freezer to fail if the thread being stopped is freezable and
try_to_freeze_tasks() is running concurrently with kthread_stop().
Parse error.
Hi!
Now that the freezer is used by kprobes, it is no longer a PM-specific piece
of
code. Move the freezer code out of kernel/power and introduce the
CONFIG_FREEZER option that will be chosen automatically if PM or KPROBES is
set.

Use TLB batching for MADV_FREE. Adds another 10-15% extra performance

Hi!
From: Rafael J. Wysocki [EMAIL PROTECTED]
Move all of the freezer-related flags to a separate field in task_struct and
introduce functions to operate them using set_bit() etc.
Looks sane to me.

This patch removes the process grouping code from the cpusets code,

Hi
PageLRU flag operation is protected by zone-lru_lock, so
SetPageLRU/ClearPageLRU
can be replaced to __SetPageLRU/__ClearPageLRU non-atomic bit operation.
Thanks.

Hi Paul,
In [patch 3/7] Containers (V8): Add generic multi-subsystem API to
containers, you have forcefully enabled interrupt in
container_init_subsys() with spin_unlock_irq() which breaks on PPC64.

No. The PG_lru flag bit is just one bit amongst many others:
