Subject: [PATCH 0/2] cgroup v2 freezer follow-up patches

Hi, Tejun!

Please, pull these two follow-up patches for the cgroup v2 freezer.

These are a fix for a spurious state transition, which could happen
due to a race condition, and a cleanup of some dead code. Both patches
were suggested by Oleg Nesterov.

Thank you!


Roman Gushchin (2):
  cgroup: prevent spurious transition into non-frozen state
  cgroup: get rid of cgroup_freezer_frozen_exit()
