The patch titled
Subject: sched,numa: add cond_resched to task_numa_work
has been removed from the -mm tree. Its filename was
schednuma-add-cond_resched-to-task_numa_work.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Rik van Riel <riel@xxxxxxxxxx>
Subject: sched,numa: add cond_resched to task_numa_work
Normally task_numa_work scans over a fairly small amount of memory, but it
is possible to run into a large unpopulated part of virtual memory, with
no pages mapped. In that case, task_numa_work can run for a while, and it
may make sense to reschedule as required.
