[Andrew Morton]

The quilt patch titled
Subject: kmsan: use ALIGN_DOWN() in kmsan_get_metadata()
has been removed from the -mm tree. Its filename was
kmsan-use-align_down-in-kmsan_get_metadata.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: kmsan: use ALIGN_DOWN() in kmsan_get_metadata()
Date: Fri, 21 Jun 2024 13:34:58 +0200

Improve the readability by replacing the custom aligning logic with
ALIGN_DOWN(). Unlike other places where a similar sequence is used, there
is no size parameter that needs to be adjusted, so the standard macro
fits.
