Jason suggests a better name in the other thread.
I would prefer something that simply adds more pins to an already pinned
folio. Much easier to get.
Yes, but also nobody should ever want to do that operation, it should
always be part of some kind of "splitting" sort of behavior..
I remember patches from Dave Howells that needed that for O_DIRECT
handling. Never say never ;)
Adding is much more intuitive than splitting ... just like we add
references when splitting a THP, using folio_ref_add().
