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” - https://syzkaller.appspot.com/bug?id=fe2fee189f1f8babd95615dcbb57871d6d18920a [2] “WARNING in cgroup_apply_control_disable” - https://syzkaller.appspot.com/bug?id=ba5a3ed954137643a9337f90782c90e90ba302ed -- My best regards to you.
