io_uring: ensure that fsnotify is always called

io_uring: ensure that fsnotify is always called

commit f63cf5192fe3418ad5ae1a4412eba5694b145f79 upstream.

Ensure that we call fsnotify_modify() if we write a file, and that we
do fsnotify_access() if we read it. This enables anyone using inotify
on the file to get notified.

Ditto for fallocate, ensure that fsnotify_modify() is called.
