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. [1] “INFO: task hung in exit_mm” - https://syzkaller.appspot.com/bug?id=dd115babf1498c3370fab8758d58940b7c6bffa4 [2] “INFO: task hung in do_exit” - https://syzkaller.appspot.com/bug?id=3e6c42e24155e5f0125368e609bee32f2b7394fe -- My best regards to you. No System Is Safe! Dongliang Mu
