Dear kernel developers,
I found that on the syzbot dashboard, “WARNING: locking bug in
finish_task_switch”[1] and
"WARNING: locking bug in finish_lock_switch"[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 "finish_lock_switch";
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.
