threadgroup_change_begin()/end() is a pointless wrapper around
cgroup_threadgroup_change_begin()/end(), minus a might_sleep()
in the !CONFIG_CGROUPS=y case.
Remove the wrappery, move the might_sleep() (the down_read()
already has a might_sleep() check).
This debloats a bit and simplifies this AP
Move the following task->mm helper APIs into a new header file,
, to further reduce the size and complexity
of :
# mm_alloc():
arch/arm/mach-rpc/ecard.c
fs/exec.c
include/linux/sched/mm.h
kernel/fork.c
# __mmdrop():
arch/arc/include/asm/mmu_context.h
include/linux/sched/mm.h
ker
The length of TASK_STATE_TO_CHAR_STR was still checked using the old
link-time manual error method - convert it to BUILD_BUG_ON(). This
has a couple of advantages:
- it's more obvious what's going on
- it reduces the size and complexity of
- BUILD_BUG_ON() will fail during compilation, with
These methods don't belong into , they are neither directly
related to task_struct or are scheduler functionality.
Put them next to the other watchdog methods in .
( Arguably that header's name is a misnomer, and this patch makes it
more so - but it should be renamed in another patch. )

Only a small fraction of sched.h users actually utilizes these defines,
and they are not scheduler functionality in any case, so move them
into their separate header.

The in_vfork() function deals with task->mm, so it better belongs

include/linux/delayacct.h relies on 'struct taskstats' but does
not include the header that defines it.
This worked so far because files that included
also happened to include other headers that included
uapi/linux/taskstats.h.
Fix it.

Collect the various scheduler and task state debugging APIs scattered
around into the new header.
In particular the show_regs() and show_stack() prototype affects many files,
update them.
