[merged] mm-memcontrol-make-cgroup_memory_nokmem-static.patch removed from -mm tree

[akpm]

The patch titled
     Subject: mm: memcontrol: make cgroup_memory_nokmem static
has been removed from the -mm tree.  Its filename was
     mm-memcontrol-make-cgroup_memory_nokmem-static.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Muchun Song <songmuchun@bytedance.com>
Subject: mm: memcontrol: make cgroup_memory_nokmem static

commit 494c1dfe855e ("mm: memcg/slab: create a new set of kmalloc-cg-<n>
caches") makes cgroup_memory_nokmem global, however, it is unnecessary
because there is already a function mem_cgroup_kmem_disabled() which
exports it.

Just make it static and replace it with mem_cgroup_kmem_disabled() in
mm/slab_common.c.
