Subject: mm/hugetlb.c: correct missing private flag clearing
We should clear the page's private flag when returing the page to the
hugepage pool. Otherwise, marked hugepage can be allocated to the user
who tries to allocate the non-reserved hugepage. If this user fail to map
this hugepage, he would try to return the page to the hugepage pool.
Since this page has a private flag, resv_huge_pages would mistakenly
increase. This patch fixes this situation.
