syz-executor149/10558 is trying to acquire lock:

ffffe8ffffc41588 (&loc_l->lock){....}-{2:2}, at: bpf_lru_push_free+0x33b/0xbb0 kernel/bpf/bpf_lru_list.c:553

but task is already holding lock:

ffffe8ffffc41588 (&loc_l->lock){....}-{2:2}, at: bpf_lru_pop_free+0x1ab/0x19b0 kernel/bpf/bpf_lru_list.c:496

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

       CPU0
       ----
  lock(&loc_l->lock);
  lock(&loc_l->lock);

 *** DEADLOCK ***

 May be due to missing lock nesting notation
