Subject: [PATCH 0/2] Cpuset hardwall flag:  Introduction
Date: Tue, 04 Mar 2008 23:52:37 -0800	[thread overview]
Message-ID: <20080305075237.608599000@menage.corp.google.com> (raw)

Currently the cpusets mem_exclusive flag is overloaded to mean both
"no-overlapping" and "no GFP_KERNEL allocations outside this cpuset".

These patches add a new mem_hardwall flag with just the allocation
restriction part of the mem_exclusive semantics, without breaking
backwards-compatibility for those who continue to use just
mem_exclusive. Additionally, the cgroup control file registration for
cpusets is cleaned up to reduce boilerplate.
