Watching for changes to a CIFS directory

Watching for changes to a CIFS directory

[Ray Van Dolson]

I'd like to watch a CIFS mounted directory for changes (files being
created in specific).

Does the CIFS client have working support for either INOTIFY or
DNOTIFY?  From perusing the mailing list, it seems that INOTIFY support
is not present, but there was discussion on implementing DNOTIFY
support some time back[1].  I'm not clear if that was ever partially or
fully implemented.

My current test scripts are using DNOTIFY and are not working with the
CIFS client included in RHEL5, Fedora 13 or Fedora 14.

Thanks,
Ray

inotify code would not be hard to finish - at one time before the vfs
api changed
(to inotify from dnotify) cifs had experimental dnotify code, but it does have
the worker functions for this.   I would be very willing to look at patches
for this ...

Thanks Steve.  If only I had the skills to create the patches!

Appreciate the info.
