From: Vladimir Davydov <vdavydov.dev@gmail.com>
Date: Sat, 1 Oct 2016 16:39:09 +0300
Subject: mm: memcontrol: use special workqueue for creating per-memcg caches
Origin: https://patchwork.kernel.org/patch/9361853/
Bug: https://bugzilla.kernel.org/show_bug.cgi?id=172981
Creating a lot of cgroups at the same time might stall all worker
threads with kmem cache creation works, because kmem cache creation is
done with the slab_mutex held. The problem was amplified by commits
801faf0db894 ("mm/slab: lockless decision to grow cache") in case of
SLAB and 81ae6d03952c ("mm/slub.c: replace kick_all_cpus_sync() with
synchronize_sched() in kmem_cache_shrink()") in case of SLUB, which
increased the maximal time the slab_mutex can be held.
To prevent that from happening, let's use a special ordered single
threaded workqueue for kmem cache creation. This shouldn't introduce any
functional changes regarding how kmem caches are created, as the work
function holds the global slab_mutex during its whole runtime anyway,
making it impossible to run more than one work at a time. By using a
single threaded workqueue, we just avoid creating a thread per each
work. Ordering is required to avoid a situation when a cgroup's work is
put off indefinitely because there are other cgroups to serve, in other
words to guarantee fairness.
