buffer: add b_folio as an alias of b_page
Patch series "Start converting buffer_heads to use folios".
I was hoping that filesystems would convert from buffer_heads to iomap,
but that's not happening particularly quickly. So the buffer_head
infrastructure needs to be converted from being page-based to being
folio-based.
This patch (of 12):
Buffer heads point to the allocation (ie the folio), not the page. This
is currently the same thing for all filesystems that use buffer heads, so
this is a safe transitional step.
