+Subject: [PATCH] ZEN: mm: Don't hog the CPU and zone lock in rmqueue_bulk()
+
+There is noticeable scheduling latency and heavy zone lock contention
+stemming from rmqueue_bulk's single hold of the zone lock while doing
+its work, as seen with the preemptoff tracer. There's no actual need for
+rmqueue_bulk() to hold the zone lock the entire time; it only does so
+for supposed efficiency. As such, we can relax the zone lock and even
+reschedule when IRQs are enabled in order to keep the scheduling delays
+and zone lock contention at bay. Forward progress is still guaranteed,
+as the zone lock can only be relaxed after page removal.
+
+With this change, rmqueue_bulk() no longer appears as a serious offender
+in the preemptoff tracer, and system latency is noticeably improved.
