WARNING: possible recursive locking detected
6.9.0-rc5-syzkaller-00159-gc942a0cd3603 #0 Not tainted
--------------------------------------------
syz-executor.1/6402 is trying to acquire lock:
ffff88807fbb41d8 (&qs->lock){-.-.}-{2:2}, at: queue_stack_map_push_elem+0x1ae/0x660 kernel/bpf/queue_stack_maps.c:210

but task is already holding lock:
ffff8880214e51d8 (&qs->lock){-.-.}-{2:2}, at: queue_stack_map_push_elem+0x1ae/0x660 kernel/bpf/queue_stack_maps.c:210

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
