From: Joonsoo Kim <js1304@xxxxxxxxx>
Subject: mm: correct return value of migrate_pages()
migrate_pages() should return number of pages not migrated or error code.
When unmap_and_move return -EAGAIN, outer loop is re-execution without
initialising nr_failed. This makes nr_failed over-counted.
So this patch correct it by initialising nr_failed in outer loop.
