WARNING: possible recursive locking detected

--------------------------------------------
syz-executor.1/14270 is trying to acquire lock:

ffff88808e623130 (&runtime->sleep){..-.}-{2:2}, at: io_poll_double_wake+0x143/0x3b0 fs/io_uring.c:4730

but task is already holding lock:

ffff88804b63d130 (&runtime->sleep){..-.}-{2:2}, at: __wake_up+0xb8/0x150 kernel/sched/wait.c:142

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

       CPU0
       ----
  lock(&runtime->sleep);
  lock(&runtime->sleep);

 *** DEADLOCK ***

 May be due to missing lock nesting notation
