Subject: [PATCH] fix oom killer kills current every time if there is memory-less-node take2
X-Git-Tag: v2.6.20-rc3~48
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=96ac5913f4e45c6a1b98350f2c0a8bb3abe2646a;p=pandora-kernel.git

[PATCH] fix oom killer kills current every time if there is memory-less-node take2

constrained_alloc(), which is called to detect where oom is from, checks
passed zone_list().  If zone_list doesn't include all nodes, it thinks oom
is from mempolicy.

But there is memory-less-node.  memory-less-node's zones are never included
in zonelist[].

contstrained_alloc() should get memory_less_node into count.  Otherwise, it
always thinks 'oom is from mempolicy'.  This means that current process
dies at any time.  This patch fix it.
