------------------------------------------------------
syz-fuzzer/5058 is trying to acquire lock:
ffffffff8d79e758 ((console_sem).lock){-.-.}-{2:2}, at: down_trylock+0x12/0x70 kernel/locking/semaphore.c:139

but task is already holding lock:
ffff8880b952c9d8 (hrtimer_bases.lock){-.-.}-{2:2}, at: __run_hrtimer kernel/time/hrtimer.c:1696 [inline]
ffff8880b952c9d8 (hrtimer_bases.lock){-.-.}-{2:2}, at: __hrtimer_run_queues+0x2c0/0xc20 kernel/time/hrtimer.c:1756

which lock already depends on the new lock.


the existing dependency chain (in reverse order) is:

other info that might help us debug this:

Chain exists of:
  (console_sem).lock --> &rt_b->rt_runtime_lock --> hrtimer_bases.lock

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(hrtimer_bases.lock);
                               lock(&rt_b->rt_runtime_lock);
                               lock(hrtimer_bases.lock);
  lock((console_sem).lock);
