Subject: [2/3] sys_move_pages: Do not fall back to other nodes
Date: Tue, 8 Aug 2006 09:34:48 -0700 (PDT) [thread overview]
Message-ID: <Pine.LNX.4.64.0608080933510.27620@schroedinger.engr.sgi.com> (raw)
In-Reply-To: <Pine.LNX.4.64.0608080930380.27620@schroedinger.engr.sgi.com>
If the user specified a node where we should move the page to then
we really do not want any other node.
