-----------------------------------------------------
syz-executor321/5079 [HC0[0]:SC0[0]:HE0:SE1] is trying to acquire:
ffff888079894d98 (&f->f_owner.lock){...-}-{2:2}, at: send_sigio+0x33/0x360 fs/fcntl.c:796

and this task is already holding:
ffff888022b4b018 (&new->fa_lock){....}-{2:2}, at: kill_fasync_rcu fs/fcntl.c:1008 [inline]
ffff888022b4b018 (&new->fa_lock){....}-{2:2}, at: kill_fasync+0x19e/0x4d0 fs/fcntl.c:1029
which would create a new lock dependency:
 (&new->fa_lock){....}-{2:2} -> (&f->f_owner.lock){...-}-{2:2}

but this new dependency connects a HARDIRQ-irq-safe lock:
 (&dev->event_lock#2){-...}-{2:2}

other info that might help us debug this:

Chain exists of:
  &dev->event_lock#2 --> &new->fa_lock --> tasklist_lock

 Possible interrupt unsafe locking scenario:
