syz.4.2363/15651 [HC0[0]:SC0[0]:HE0:SE1] is trying to acquire:
ffffffff8e60a058 (tasklist_lock){.+.+}-{2:2}, at: send_sigurg+0x144/0x430 fs/fcntl.c:970

ffff888026da2420 (&f_owner->lock){....}-{2:2}, at: send_sigurg+0x58/0x430 fs/fcntl.c:954
which would create a new lock dependency:

other info that might help us debug this:

Chain exists of:
  &dev->event_lock#2 --> &f_owner->lock --> tasklist_lock

 Possible interrupt unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(tasklist_lock);

                               lock(&dev->event_lock#2);
                               lock(&f_owner->lock);
  <Interrupt>
