These functions still only work in PAGE_SIZE chunks, but there are
fewer conversions from tail to head pages as a result of this patch.

Isn't this only needed in the BUFFER_HEAD case?

On second thoughts, this is silly.  __block_write_begin_int() doesn't
want the precise page (because it constructs buffer_heads and attaches
them to the passed-in page).  I should just pass &folio->page here.
And __block_write_begin_int() should be converted to take a folio
at some point.
