From 2dca53a9dabe76f49209c9128313347510416c68 Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Tue, 16 Oct 2007 01:25:33 -0700 Subject: [PATCH] Memoryless nodes: Uncached allocator updates The checks for node_online in the uncached allocator are made to make sure that memory is available on these nodes. Thus switch all the checks to use N_HIGH_MEMORY and to N_ONLINE.
