[PATCH 2/6] hugetlbfs: fix cannot migrate the fallocated HugeTLB page

Because we only can isolate a active page via isolate_huge_page() and hugetlbfs_fallocate() forget to mark it as active, we cannot isolate and migrate those pages. Fixes: 70c3547e36f5 (hugetlbfs: add hugetlbfs_fallocate()) Signed-off-by: Muchun Song --- fs/hugetlbfs/inode.c | 5 +++-- 1 file cha
