The quilt patch titled
Subject: filemap: convert filemap_range_has_page() to use a folio
has been removed from the -mm tree. Its filename was
filemap-convert-filemap_range_has_page-to-use-a-folio.patch
This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: filemap: convert filemap_range_has_page() to use a folio

The folio isn't returned from this function, so this is an entirely
internal change.
