Crash: possible deadlock in do_fcntl (log)
Repro: C syz .config

Sample crash report:

========================================================
WARNING: possible irq lock inversion dependency detected
5.10.0-rc7-syzkaller #0 Not tainted
--------------------------------------------------------
syz-executor273/8504 just changed the state of lock:
ffff88802594f2b8 (&f->f_owner.lock){.+..}-{2:2}, at: f_getown_ex fs/fcntl.c:206 [inline]
ffff88802594f2b8 (&f->f_owner.lock){.+..}-{2:2}, at: do_fcntl+0x8ab/0x1070 fs/fcntl.c:387
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-executor273/8504.
