Hi,

Syzbot reports a possible irq lock inversion dependency:
https://syzkaller.appspot.com/bug?id=923cfc6c6348963f99886a0176ef11dcc429547b

While investigating this error, I discovered that multiple similar lock inversion scenarios can occur. Hence, this series addresses potential deadlocks for two classes of locks, one in each patch:

1. Fix potential deadlocks for &fown_struct.lock

2. Fix potential deadlock for &fasync_struct.fa_lock

Best wishes,
Desmond

  fcntl: fix potential deadlocks for &fown_struct.lock
  fcntl: fix potential deadlock for &fasync_struct.fa_lock
