Subject: [PATCH 0/2] mm: memcontrol: cleanup and optimize for accounting params
Date: Tue, 30 Aug 2022 13:59:47 +0800 [thread overview]
Message-ID: <20220830055949.12640-1-ryncsn@gmail.com> (raw)
From: Kairui Song <kasong-1Nz4purKYjRBDgjK7y7TUQ@public.gmane.org>
Patch 1/2 changes the behavior of kmem accounting a bit, making
it either globally enabled or globally disabled by boot params and
no longer affected by the creation of the first non-root cgroup.
This might be a bit arguable though.
Patch 2/2 optimizes some hot paths by making cgroup_memory_noswap a
static key, benchmark shows swap paths now have a ~4% lower overhead.
