There are two commits introducing the same declaration, 92c09c041f15
("mm: declare some external symbols") and 5b41d92437f1
("ext4: implement writeback livelock avoidance using page tagging"),
they are all introducing declaration for tag_pages_for_writeback(), just
lines apart.
One declaration is enough.
