WARNING: possible recursive locking detected

--------------------------------------------
syz-executor265/3570 is trying to acquire lock:
ffff8880b9b35bb8 (lock#8){+.+.}-{2:2}, at: local_lock_acquire+0xd/0x170 include/linux/local_lock_internal.h:28

but task is already holding lock:
ffff8880b9b35bb8 (lock#8){+.+.}-{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#8);
  lock(lock#8);

 *** DEADLOCK ***

 May be due to missing lock nesting notation
