Subject: [PATCH 3/7] Add NR_MLOCK ZVC
Date: Wed, 14 Feb 2007 17:25:05 -0800 (PST) [thread overview]
Message-ID: <20070215012505.5343.65950.sendpatchset@schroedinger.engr.sgi.com> (raw)
In-Reply-To: <20070215012449.5343.22942.sendpatchset@schroedinger.engr.sgi.com>
Basic infrastructure to support NR_MLOCK
Add a new ZVC to support NR_MLOCK. NR_MLOCK counts the number of
mlocked pages taken off the LRU. Get rid of wrong calculation
of cache line size in the comments in mmzone.h.
