filemap: add filemap_get_folios_contig()
Patch series "Convert to filemap_get_folios_contig()", v3.
This patch series replaces find_get_pages_contig() with
filemap_get_folios_contig().
This patch (of 7):
This function is meant to replace find_get_pages_contig().
Unlike find_get_pages_contig(), filemap_get_folios_contig() no longer
takes in a target number of pages to find - It returns up to 15 contiguous
folios.
To be more consistent with filemap_get_folios(),
filemap_get_folios_contig() now also updates the start index passed in,
and takes an end index.
