Merge tag 'cgroup-for-7.3-rc1-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup fixes from Tejun Heo:
- After cgroup.kill was written to a cgroup, every child cloned into it
with CLONE_INTO_CGROUP was spuriously killed because the fork path
snapshotted the kill counter before resolving the target cgroup
- Releasing an isolated cpuset partition dropped the isolation of CPUs
isolated on the kernel command line
- Selftest and documentation fixes
