If that's the case then there is precedent (e.g. sched_op, physdev_op,
evtchn_op) for renaming the existing thing FOO_compat and taking over
the name with the new semantics.

That's certainly better than _new->_newer->really_new etc. If you must
go down that route then adding a number seems preferable.

Ian.
