From: Mel Gorman <mgorman@xxxxxxxxxxxxxxxxxxx>
Subject: mm, compaction: Capture a page under direct compaction -fix
Vlastimil pointed out that a check for isolation is redundant in
__free_one_page as compaction_capture checks for it.
This is a fix for the mmotm patch
mm-compaction-capture-a-page-under-direct-compaction.patch
