[PATCH] mm, compaction: Capture a page under direct compaction -fix

From: Mel Gorman
Date: Fri Feb 01 2019 - 09:38:59 EST


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
