    > CIFS doesn't support symlinks (they just appear as the referenced file), so I've had applications that scan the filesystem recurse indefinitely due to symlinked directories on a CIFS share appearing as hard-linked directories on the client. This doesn't happen when the filesystem is accessed via NFS.

    Sigh... So please explain how it would be useful to export that
    particular filesystem through _both_ CIFS and NFS?

    My point was that in most circumstances you want to export either
    through CIFS or through NFS, but very rarely both.

    I also made the point that converting ctime into a creation time would
    break NFS, but it would be a limited breakage, mainly affecting the
    client's ability to detect ACL changes, and possibly causing the inode
    to get temporarily updated with stale attribute information on occasion
    due to out-of-order RPC replies.
