syz-executor.0/3957 is trying to acquire lock:
ffffffff853fac98 ((console_sem).lock){....}-{2:2}, at: down_trylock+0xe/0x70

but task is already holding lock:
ffff88800ea9ac20 (&ctx->lock){....}-{2:2}, at: __perf_event_task_sched_out+0x53b/0x18d0

which lock already depends on the new lock.

other info that might help us debug this:

Chain exists of:

 Possible unsafe locking scenario:
