Subject: [PATCH] slub: add missing kmem cgroup support to kmem_cache_free_bulk
Date: Thu, 29 Oct 2015 14:05:31 +0100 [thread overview]
Message-ID: <20151029130531.15158.58018.stgit@firesoul> (raw)
Initial implementation missed support for kmem cgroup support
in kmem_cache_free_bulk() call, add this.
If CONFIG_MEMCG_KMEM is not enabled, the compiler should
be smart enough to not add any asm code.
