Subject: [RFC PATCH 1/9] mm: do not add anon pages to LRU
Date: Tue, 11 Sep 2018 13:36:08 +0800 [thread overview]
Message-ID: <20180911053616.6894-2-aaron.lu@intel.com> (raw)
In-Reply-To: <20180911053616.6894-1-aaron.lu@intel.com>
For the sake of testing purpose, do not add anon pages to LRU to
avoid LRU lock so we can test zone lock exclusively.
