Subject: [RFC 04/13] Memoryless Nodes: No need for kswapd
Date: Thu, 14 Jun 2007 00:50:30 -0700 [thread overview]
Message-ID: <20070614075334.990871341@sgi.com> (raw)
In-Reply-To: 20070614075026.607300756@sgi.com
[-- Attachment #1: nodeless_no_kswapd --]
[-- Type: text/plain, Size: 867 bytes --]
A node without memory does not need a kswapd. So use the memory map instead
of the online map to start kswapd.
