Dear kernel developers,
I found that on the syzbot dashboard, “possible deadlock in console_lock_spinning_enable”[1] and "possible deadlock in console_unlock"[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 "console_lock_spinning_enable"; 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.
