From ecb256f815232b35ae8382cff36ca8ce0bbd077e Mon Sep 17 00:00:00 2001 From: "Volodymyr G. Lukiianyk" Date: Thu, 13 Jan 2011 15:46:26 -0800 Subject: [PATCH] mm: set correct numa_zonelist_order string when configured on the kernel command line When numa_zonelist_order parameter is set to "node" or "zone" on the command line it's still showing as "default" in sysctl. That's because early_param parsing function changes only user_zonelist_order variable. Fix this by copying user-provided string to numa_zonelist_order if it was successfully parsed.
