From: Paul Jackson Date: Sun, 8 Jan 2006 09:00:56 +0000 (-0800) Subject: [PATCH] cpusets: swap migration interface X-Git-Tag: v2.6.16-rc1~884 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=45b07ef31d1182d2cfde7711327e3afb268bb1ac;p=pandora-kernel.git [PATCH] cpusets: swap migration interface Add a boolean "memory_migrate" to each cpuset, represented by a file containing "0" or "1" in each directory below /dev/cpuset. It defaults to false (file contains "0"). It can be set true by writing "1" to the file. If true, then anytime that a task is attached to the cpuset so marked, the pages of that task will be moved to that cpuset, preserving, to the extent practical, the cpuset-relative placement of the pages. Also anytime that a cpuset so marked has its memory placement changed (by writing to its "mems" file), the tasks in that cpuset will have their pages moved to the cpusets new nodes, preserving, to the extent practical, the cpuset-relative placement of the moved pages.
