Merge tag 'cgroup-for-7.3-rc6-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup fixes from Tejun Heo:
- During CPU offline, the active mask drops the CPU before cpuset
updates the effective CPUs, so a task placement in that window could
find no active CPU in the top cpuset and dereference NULL. Restore
the NULL check.
- The cpuset v2-mode test read the subsystem's root pointer, which is
stale during a cgroup filesystem rebind, and the hotplug handler
evaluated it before taking the cpuset mutex. Record the mode in a
flag and test it under the mutex.
