Dear kernel developers,

I found that on the syzbot dashboard, “WARNING in
cgroup_finalize_control” [1] and "WARNING in
cgroup_apply_control_disable" [2] should share the same root cause.

The reasons for the above statement:
1) the stack trace is the same, and this title difference is due to
the inline property of "cgroup_apply_control_disable";
2) their PoCs are the same as each other;

If you can have any issues with this statement or our information is
useful to you, please let us know. Thanks very much.

[1] “WARNING in cgroup_finalize_control” -

[2] “WARNING in cgroup_apply_control_disable” -

My best regards to you.
