Subject: "INFO: task hung in exit_mm" and "INFO: task hung in do_exit" should be duplicate crash reports
Date: Thu, 21 Jan 2021 13:58:58 +0800	[thread overview]
Message-ID: <CAD-N9QXHkGkwihX=E7HAnDs3L90=Q5FerLb0mJhdXMb+pH-tew@mail.gmail.com> (raw)

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.
