[Andrew Morton <akpm@linux-foundation.org>]

The quilt patch titled
     Subject: mm: apply __must_check to vmap_pages_range_noflush()
has been removed from the -mm tree.  Its filename was
     mm-apply-__must_check-to-vmap_pages_range_noflush.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: apply __must_check to vmap_pages_range_noflush()
Date: Thu, 13 Apr 2023 15:12:23 +0200

To prevent errors when vmap_pages_range_noflush() or
__vmap_pages_range_noflush() silently fail (see the link below for an
example), annotate them with __must_check so that the callers do not
unconditionally assume the mapping succeeded.
