Subject: [PATCH] mm, hugetlb: correct missing private flag clearing
Date: Mon, 30 Sep 2013 16:59:44 +0900 [thread overview]
Message-ID: <1380527985-18499-1-git-send-email-iamjoonsoo.kim@lge.com> (raw)
We should clear the page's private flag when returing the page to
the page allocator or the hugepage pool. This patch fixes it.

Hello, Andrew.
I sent the new version of commit ('07443a8') before you did pull request,
but it isn't included. It may be losted :)
So I send this fix. IMO, this is good for v3.12.
Thanks.
