Subject: [RFC 03/13] OOM: use the node_memory_map instead of constructing one on the fly
Date: Thu, 14 Jun 2007 00:50:29 -0700 [thread overview]
Message-ID: <20070614075334.761001237@sgi.com> (raw)
In-Reply-To: <20070614075026.607300756@sgi.com>
[-- Attachment #1: nodeless_oom_kill --]
[-- Type: text/plain, Size: 1102 bytes --]
constrained_alloc() builds its own memory map for nodes with memory.
We have that available in node_memory_map now. So simplify the code.
