The patch titled hotplug cpu move tasks in empty cpusets to parent node_online_map fix has been removed from the -mm tree. Its filename was hotplug-cpu-move-tasks-in-empty-cpusets-to-parent-node_online_map-fix.patch This patch was dropped because it was folded into hotplug-cpu-move-tasks-in-empty-cpusets-to-parent.patch The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: hotplug cpu move tasks in empty cpusets to parent node_online_map fix From: Cliff Wickman <cpw@xxxxxxx> As of the October 2007 kernel/cpuset.c patch "Memoryless nodes: Use N_HIGH_MEMORY for cpusets", cpuset nodes are relative to the nodes with (HIGH) memory, not relative to all nodes in node_online_map.
