I'm working on enabling fsnotify for fuse. The sending of a watch/mask
to userspace works, and the fuse filesystem can forward the watch to
it's backend.
Reporting delete events back to the kernel works with the help of one
existing call fuse_lowlevel_notify_delete. There is no existing call
to report a create, so I'm working on that.

( at this moment I'm trying to enable the most simple events : delete
and create of an entry in a directory which is watched).
