Subject: mm/mempolicy: correct putback method for isolate pages if failed
From: Joonsoo Kim <iamjoonsoo.kim@xxxxxxx>
commit b0e5fd7359f1ce8db4ccb862b3aa80d2f2cbf4d0 upstream.
queue_pages_range() isolates hugetlbfs pages and putback_lru_pages()
can't handle these. We should change it to putback_movable_pages().
Naoya said that it is worth going into stable, because it can break
in-use hugepage list.
