When we have a page fault for the address which is backed by a hugepage under migration, the kernel can't wait correctly until the migration finishes. This is because pte_offset_map_lock() can't get a correct migration entry for hugepage. This patch adds migration_entry_wait_huge() to separate code path between normal pages and hugepages. ChangeLog v2: - remove dup in migrate_entry_wait_huge() Signed-off-by: Naoya Horiguchi <n-horiguchi@xxxxxxxxxxxxx>
