I'm happy for it to be an ioctl interface - even an XFS specific interface if you want to go that route, Sage - and it probably should emit a warning to syslog first time it is used so there is trace for bug triage purposes. i.e. we know the app is not using mtime updates, so bug reports that are the result of mtime mishandling don't result in large amounts of wasted developer time trying to understand them...
