[merged mm-hotfixes-stable] selftests-damon-sysfs_memcg_path_leak-define-ksft_skip.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: selftests/damon/sysfs_memcg_path_leak: define ksft_skip
has been removed from the -mm tree.  Its filename was
     selftests-damon-sysfs_memcg_path_leak-define-ksft_skip.patch

This patch was dropped because it was merged into the mm-hotfixes-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: selftests/damon/sysfs_memcg_path_leak: define ksft_skip
Date: Mon, 02 Nov 2026 06:46:26 -0800

sysfs_memcg_path_leak test uses $ksft_skip without defining it.  As a
result, the test is marked as passed while it was skipped, like below.

    $ ./sysfs_memcg_path_leak.sh
    Run as root
    $ echo $?
    0

Users who run the test could therefore wrongly believe the test was run
and passed while it was skipped.

Define the value at the beginning of the test.  After this patch, the
exit code reflects the skip.

    $ ./sysfs_memcg_path_leak.sh
    Run as root
    $ echo $?
    4
