WARNING: possible recursive locking detected

--------------------------------------------
syz-executor.1/11611 is trying to acquire lock:
ffff88806547b1d8 (&qs->lock){..-.}-{2:2}, at: queue_stack_map_push_elem+0x1b2/0x660 kernel/bpf/queue_stack_maps.c:210

but task is already holding lock:
ffff88806547b1d8 (&qs->lock){..-.}-{2:2}, at: __queue_map_get+0x14b/0x4d0 kernel/bpf/queue_stack_maps.c:105

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

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

 *** DEADLOCK ***

 May be due to missing lock nesting notation
