[merged mm-stable] selftests-mm-skip-mlock-tests-if-nobody-user-cant-read-it.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: selftests/mm: skip mlock tests if nobody user can't read it
has been removed from the -mm tree.  Its filename was
     selftests-mm-skip-mlock-tests-if-nobody-user-cant-read-it.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: selftests/mm: skip mlock tests if nobody user can't read it
Date: Tue, 11 Mar 2025 13:18:22 +0000

If running from a directory that can't be read by unprivileged users,
executing on-fault-test via the nobody user will fail.

The kselftest build does give the file the correct permissions, but after
being installed it might be in a directory without global execute
permissions.

Since the script can't safely fix that, just skip if it happens.  Note
that the stderr of the `ls` command is unfiltered meaning the user sees a
"permission denied" error that can help inform them why the test was
skipped.
