syz-executor.0/12312 is trying to acquire lock:
 (event_mutex){+.+.}, at: [<ffffffff815bd374>] ftrace_profile_set_filter+0x64/0x1c0 kernel/trace/trace_events_filter.c:2268

but task is already holding lock:
 (&cpuctx_mutex){+.+.}, at: [<ffffffff81636c4d>] perf_event_ctx_lock_nested+0x14d/0x2c0 kernel/events/core.c:1241

which lock already depends on the new lock.

other info that might help us debug this:

Chain exists of:
  event_mutex --> pmus_lock --> &cpuctx_mutex

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(&cpuctx_mutex);
                               lock(pmus_lock);
                               lock(&cpuctx_mutex);
  lock(event_mutex);
