--------------------------------------------
syz-executor.1/9597 is trying to acquire lock:

but task is already holding lock:

other info that might help us debug this:
 Possible unsafe locking scenario:

       CPU0
       ----
  lock(&ni->ni_lock#2);
  lock(&ni->ni_lock#2);

 *** DEADLOCK ***

 May be due to missing lock nesting notation
