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.
