Linus Torvalds 0d32b3ec5f 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.

* tag 'cgroup-for-7.3-rc6-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup:
  cgroup/cpuset: Call is_in_v2_mode() after acquiring cpuset_mutex in cpuset_handle_hotplug()
  cgroup/cpuset: Handle cpu hotplug race in guarantee_active_cpus()
  cgroup/cpuset: Don't access cpuset_cgrp_subsys.root in is_in_v2_mode()
