Sample crash report:

========================================================
WARNING: possible irq lock inversion dependency detected
5.13.0-rc2-syzkaller #0 Not tainted
--------------------------------------------------------
syz-executor166/8419 just changed the state of lock:
ffff8880173ebcb8 (&f->f_owner.lock){.+..}-{2:2}, at: f_getown+0x22/0x210 fs/fcntl.c:153
but this lock was taken by another, HARDIRQ-safe lock in the past:
 (&dev->event_lock){-...}-{2:2}


and interrupts could create inverse lock ordering between them.


other info that might help us debug this:
Chain exists of:
  &dev->event_lock --> &new->fa_lock --> &f->f_owner.lock

 Possible interrupt unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(&f->f_owner.lock);
                               local_irq_disable();
                               lock(&dev->event_lock);
                               lock(&new->fa_lock);
  <Interrupt>
    lock(&dev->event_lock);

 *** DEADLOCK ***

no locks held by syz-executor166/8419.
