syz-executor.3/10624 is trying to acquire lock:

which lock already depends on the new lock.

other info that might help us debug this:

Chain exists of:
  &ni->ni_lock#3 --> &wnd->rw_lock/1 --> &ni->file.run_lock#2

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(&ni->file.run_lock#2);
                               lock(&wnd->rw_lock/1);
                               lock(&ni->file.run_lock#2);
  lock(&ni->ni_lock#3);
