ext3 uses rb_node = NULL; to zero rb_root. 

The problem with this is that 17d9ddc72f ("rbtree: Add support
for augmented rbtrees") in the linux-next tree adds a new field to that
struct which needs to be NULLas well.  This patch uses RB_ROOT as the
intializer so all of the relevant fields will be NULL'd.
