Okay, I don't care much about inserting spaces to align with the bracket,
but didn't like those continuation args leftward of function name above.
I'll adjust in v2, and eventually we reach a compromise.

I was expecting more resistance :) Right, I put it in huge_mm.h to be
next to your folio_prep_large_rmappable() declaration, but it doesn't
have to be there. Ooh, there's a folio_undo_large_rmappable() in
mm/internal.h, I'll move page_rmappable_folio() next to that.
