The patch titled
     Subject: mm: slab: make slab iterator functions static
has been removed from the -mm tree.  Its filename was
     mm-slab-make-slab-iterator-functions-static.patch

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

------------------------------------------------------
From: Muchun Song <songmuchun@xxxxxxxxxxxxx>
Subject: mm: slab: make slab iterator functions static

There is no external users of slab_start/next/stop(), so make them static.
And the memory.kmem.slabinfo is deprecated, which outputs nothing now, so
move memcg_slab_show() into mm/memcontrol.c and rename it to
mem_cgroup_slab_show to be consistent with other function names.
