Dear kernel developers,
I found that on the syzbot dashboard, “INFO: task hung in exit_mm”[1]
and "INFO: task hung in do_exit"[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 "exit_mm";
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.
