During global reclaim, the nr_reclaimed passed to vmpressure includes the
pages reclaimed from slab. But the corresponding scanned slab pages is
not passed. This can cause total reclaimed pages to be greater than
scanned, causing an unsigned underflow in vmpressure resulting in a
critical event b
At the end of a window period, if the reclaimed pages
is greater than scanned, an unsigned underflow can
result in a huge pressure value and thus a critical event.
Reclaimed pages is found to go higher than scanned because
of the addition of reclaimed slab pages to reclaimed in
shrink_node without

With the new authenc support, we get a harmless Kconfig warning:

Unify definitions for MIPS performance counter register fields in
mipsregs.h rather than duplicating them in perf_events and oprofile.
This will allow future patches to use them to expose performance
counters to KVM guests.

the PMC Global Control Registers (GCR) to read deep and shallow
S0ix residency.

o Upper 4kB: GCR (Global Control Registers)

This is obviously exactly how we should do this.
However since it needs the devm* helpers from the irq
subs
is still needed - but we at least don't have MM
headers in sched.h anymore, except .
Fix dependencies in files that depended on this include.

include/linux/delayacct.h relies on 'struct taskstats' but does

This worked so far because files that included

threadgroup_change_begin()/end() is a pointless wrapper around
cgroup_threadgroup_change_begin()/end(), minus a might_sleep()

Remove the wrappery, move the might_sleep() (the down_read()
already has a might_sleep() check).

The length of TASK_STATE_TO_CHAR_STR was still checked using the old

So the original intention of tsk_cpus_allowed() was to 'future-proof'
the field - but it's pretty ineffectual at that, because half of
the code uses ->cpus_allowed directly ...
Also, the wrapper makes the code longer than the original expression!
So just get rid of it. This also shrinks a bit.
Unclutter some more.
Also move the CONFIG_ARCH_WANT_BATCHED_UNMAP_TLB_FLUSH condition inside the
structure body definition, to remove a pair of #ifdefs from sched.h.

So rcupdate.h is a pretty complex header, in particular it includes

dependency that includes in ,
which prevents the isolation of from the derived

Solve part of the problem by decoupling rcupdate.h from completions:
this can be done by separating out the rc

To make those patches build cleanly prepare the scene by adding
