From: Tomasz Buchert on
These patches fixes two bugs I discovered when working with
the cgroup freezer. These patches fix them (and probably also
some other variations of them) and now the kernel passes
testcases that uncovered the bugs in the first place.

Please review.


Tomasz Buchert (3):
cgroup_freezer: Unnecessary test in cgroup_freezing_or_frozen
cgroup_freezer: Fix can_attach to prohibit moving from/to
freezing/frozen cgroups
cgroup_freezer: update_freezer_state does incorrect state
