[PATCH 6.6 0/5] [Backport] sched,freezer: Remove unnecessary warning in __thaw_task

[Chen Ridong]

From: Chen Ridong <chenridong@xxxxxxxxxx>

To fix the [1] issue, it needs to backport:
9beb8c5e77dc ("sched,freezer: Remove unnecessary warning...")
14a67b42cb6f ("Revert 'cgroup_freezer: cgroup freezing: Check if not...'").

This series aims to backport 9beb8c5e77dc. To avoid conflicts, backport the
missing patches[2].
