[Andrew Morton]

The quilt patch titled

has been removed from the -mm tree.  Its filename was
     mm-convert-isolate_page-to-mf_isolate_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: mm: convert isolate_page() to mf_isolate_folio()
Date: Wed, 8 Nov 2023 18:28:08 +0000

The only caller now has a folio, so pass it in and operate on it.  Saves
many page->folio conversions and introduces only one folio->page
conversion when calling isolate_movable_page().
