Subject: [patch 04/10] OOM: use the node_memory_map instead of constructing one on the fly
Date: Mon, 18 Jun 2007 12:20:00 -0700 [thread overview]
Message-ID: <20070618192545.072982806@sgi.com> (raw)
In-Reply-To: <20070618191956.411091458@sgi.com>

constrained_alloc() builds its own memory map for nodes with memory.
We have that available in node_memory_map now. So simplify the code.
