syz-executor.2/2562 is trying to acquire lock:
ffff888041b69130 (&runtime->sleep){..-.}-{2:2}, at: io_poll_double_wake+0x2ba/0x7c0 fs/io_uring.c:5467
but task is already holding lock:
ffff888041b6c130 (&runtime->sleep){..-.}-{2:2}, at: __wake_up_common_lock+0xb4/0x130 kernel/sched/wait.c:137
other info that might help us debug this:
Possible unsafe locking scenario:
