We should clear the page's private flag when returing the page to the page allocator or the hugepage pool. This patch fixes it.
Signed-off-by: Joonsoo Kim <iamjoonsoo.kim@lge.com> --- 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.
