Hi Richard,

Please find my response inline-

The VFS supports this feature but according to the patchsets that I
went through in which Al-Viro ripped support for the same in CIFS,
there are changes needed in the VFS to bring it back to CIFS. This is
my understanding after going through Al-Viro's patch. Correct me, if I
am wrong.

You can follow the discussion from the Samba mailing list at the below
link for the same-
 under the thread "[linux-cifs-client] [PATCH] cifs: remove dnotify
thread code "

>>To modify the CIFSFS to pass through change-notify events to
>>inotify requests that applications might be using?

If I can understand your question correctly, I can only answer that
inotify support has to provided in the lower filesystems too not just
the VFS(which it currently has) to enable this feature.
