syz-executor365/6543 [HC0[0]:SC0[0]:HE0:SE1] is trying to acquire:
ffffffff8b60a098 (tasklist_lock){.+.+}-{2:2}, at: send_sigio+0xab/0x380 fs/fcntl.c:810

and this task is already holding:
ffff8880737dbcb8 (&f->f_owner.lock){....}-{2:2}, at: send_sigio+0x24/0x380 fs/fcntl.c:796
which would create a new lock dependency:
 (&f->f_owner.lock){....}-{2:2} -> (tasklist_lock){.+.+}-{2:2}

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

other info that might help us debug this:

Chain exists of:
  &dev->event_lock --> &f->f_owner.lock --> tasklist_lock

 Possible interrupt unsafe locking scenario:
