With the recent changes to fanotify (e.g.
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=7cea2a3c505e)
has there been any additional discussion of what it would take to
allow fanotify to be supported for network/cluster fs (all major
dialects supported by cifs.ko support sending notify requests to the
server - but there is no way for cifs.ko to be told which notify
requests to send as fanotify/inotify are local only in current Linux -
unlike other OS where notify is primarily for network fs and passed
down to the fs)

Thanks,

Not sure how this is related to remote fs notifications.

It would take someone to pick up this RFC that was already posted
2 years ago:

If you wait long enough, I'll get to implementing this for FUSE some day...
But there is *really* nothing blocking cifs developers from implementing this
and writing the specialized tests. I can help with guidance.
Thanks,
Amir.

It's on my TODO list but I am dealing with some multichannel bugs at
the moment...
but would be great if someone had run into the same thing and fixed it. If not
I will revisit the question of how to do this
