rbtree-empty-nodes-have-no-color-fix

After merging the akpm tree, today's linux-next build (x86_64
allmodconfig) failed like this:

net/ceph/osd_client.c: In function 'ceph_osdc_alloc_request':
net/ceph/osd_client.c:216:2: error: implicit declaration of function 'rb_in=
it_node' [-Werror=3Dimplicit-function-declaration]

Caused by commit 753b960e52b7 ("rbtree: empty nodes have no color") from
the akpm tree interacting with commit cd43045c2de6 ("libceph: initialize
rb, list nodes in ceph_osd_request") from the ceph tree.
