The quilt patch titled
     Subject: selftests: cgroup: fix test_kmem_basic less than error

of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: selftests: cgroup: fix test_kmem_basic less than error
Date: Fri, 4 Aug 2023 15:35:29 -0400

test_kmem_basic creates 100,000 negative dentries, with each one mapping
to a slab object.  After memory.high is set, these are reclaimed through
the shrink_slab function call which reclaims all 100,000 entries.  The
test passes the majority of the time because when slab1 or current is
calculated, it is often above 0, however, 0 is also an acceptable value.
