This doesn't apply to misc-next cleanly, so I can't do my normal review, but
just swapping us over to the folio stuff in name everywhere is a valuable first
start.  I'd like to see this run through our testing infrastructure to make sure
nothing got missed.  Once you can get it to apply cleanly somewhere and validate
nothing weird got broken you can add
