The quilt patch titled
Subject: kmemleak-test: fix kmemleak_test.c build logic
has been removed from the -mm tree. Its filename was
kmemleak-test-optimize-kmemleak_testc-build-flow.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: kmemleak-test: fix kmemleak_test.c build logic
Date: Thu, 30 Mar 2023 14:09:04 +0800
kmemleak-test.c was moved to the samples directory in 1abbef4f51724
("mm,kmemleak-test.c: move kmemleak-test.c to samples dir").
If CONFIG_DEBUG_KMEMLEAK_TEST=m and CONFIG_SAMPLES is unset,
kmemleak-test.c will be unnecessarily compiled.
So move the entry for CONFIG_DEBUG_KMEMLEAK_TEST from mm/Kconfig and add a
new CONFIG_SAMPLE_KMEMLEAK in samples/ to control whether kmemleak-test.c
is built or not.
