WARNING: possible circular locking dependency detected
5.15.164-syzkaller #0 Not tainted
------------------------------------------------------
syz-executor/3574 is trying to acquire lock:
ffffffff8c9146a0 (console_owner){-...}-{0:0}, at: console_trylock_spinning+0x185/0x3f0 kernel/printk/printk.c:1879

but task is already holding lock:
ffff8880b9a2a218 (hrtimer_bases.lock){-.-.}-{2:2}, at: __run_hrtimer kernel/time/hrtimer.c:1690 [inline]
ffff8880b9a2a218 (hrtimer_bases.lock){-.-.}-{2:2}, at: __hrtimer_run_queues+0x662/0xcf0 kernel/time/hrtimer.c:1750

which lock already depends on the new lock.


the existing dependency chain (in reverse order) is:
