Subject[PATCHSET] cgroup/for-4.17: Make cgroup_rstat available to controllers
Date
Hello,

cgroup has scalable recursive stat mechanism implemented in
kernel/stat.c. It's currently only used to track cpu consumptions and
difficult to use outside of cgroup core. This patchset generalizes
the mechanism and exposes it as cgroup_rstat so that controllers can
use it.

This patchset contains the following eight patches. A follow-up
patchset will add usages.

0001-cgroup-Rename-kernel-cgroup-stat.c-to-kernel-cgroup-.patch
0002-cgroup-Rename-stat-to-rstat.patch
0003-cgroup-Distinguish-base-resource-stat-implementation.patch
0004-cgroup-Reorganize-kernel-cgroup-rstat.c.patch
0005-cgroup-Factor-out-and-expose-cgroup_rstat_-interface.patch
0006-cgroup-Replace-cgroup_rstat_mutex-with-a-spinlock.patch
0007-cgroup-Add-cgroup_subsys-css_rstat_flush.patch
0008-cgroup-Add-memory-barriers-to-plug-cgroup_rstat_upda.patch

This patchset is also available in the following git branch.

git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup.git review-cgroup_rstat

diffstat follows.
