I would adjust the subject, as it sounds like the patch does the whole
workingset detection, not just preparation.
How about:

mm/workingset: prepare the workingset infrastructure for anon LRU

How about:
To prepare for this, this patch splits workingset event counters for refault,
activate and restore into anon and file variants, as well as the refaults
counter in struct lruvec.

Again, v6 update info shouldn't go to changelog. In this case I think it doesn't
need mentioning at all, at least not in this patch.
