WARNING: possible recursive locking detected
5.15.164-syzkaller #0 Not tainted
--------------------------------------------
syz.1.2613/11280 is trying to acquire lock:
ffff8880b9a35bb8 (lock#11){+.+.}-{2:2}, at: local_lock_acquire+0xd/0x170 include/linux/local_lock_internal.h:28

but task is already holding lock:
ffff8880b9a35bb8 (lock#11){+.+.}-{2:2}, at: local_lock_acquire+0xd/0x170 include/linux/local_lock_internal.h:28

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

       CPU0
       ----
  lock(lock#11
);
  lock(lock
#11);

 *** DEADLOCK ***

 May be due to missing lock nesting notation
