Subject: [RFC][PATCH 0/8] mm: freshen percpu pageset code
Date: Tue, 15 Oct 2013 13:35:36 -0700 [thread overview]
Message-ID: <20131015203536.1475C2BE@viggo.jf.intel.com> (raw)
The percpu pageset (pcp) code is looking a little old and
neglected these days. This set does a couple of these things (in
order of importance, not order of implementation in the series):
1. Change the default pageset pcp->high value from 744kB
to 512k. (see "consolidate high-to-batch ratio code")
2. Allow setting of vm.percpu_pagelist_fraction=0, which
takes you back to the boot-time behavior
3. Resolve inconsistencies in the way the boot-time and
sysctl pcp code works.
4. Clarify some function names and code comments.
