CHROMIUM: Reapply "cgroup_freezer: cgroup_freezing: Check if not frozen"
This reverts commit 8594813132f02bb569380461346583918b6e5e86.
The reverted commit regressed several suspend/resume tests on dedede
with the below error:
Unhandled KernelError: kernel: WARNING: [...] kernel/freezer.c:199 __thaw_task+0xc5/0xd0
The regression's probable cause is an incomplete backport. The reverted
commit was a backport from master to v6.1.147. Its commit message
mentions a commit dependency (a "previous patch"), but the dependency is
missing in linux-6.1.y as of v6.1.162.
commit 8594813132f02bb569380461346583918b6e5e86
Subject: Revert "cgroup_freezer: cgroup_freezing: Check if not frozen"
[...]
The warning has been removed in the previous patch. This patch revert the
commit cff5f49d433f ("cgroup_freezer: cgroup_freezing: Check if not
frozen") to complete the fix.
A scan of linux-6.6.y history suggests the dependency set contains at
least the following commits:
