Subject[PATCH 5.15 066/230] io_uring: ensure that fsnotify is always called
Date
From: Jens Axboe <axboe@kernel.dk>

[ Upstream commit f63cf5192fe3418ad5ae1a4412eba5694b145f79 ]

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.
