From: "Liu, Changcheng" <[email protected]> RCU's nxttail has been optimized to be a rcu_segcblist, which is a multi-tailed linked list with macros defined for the indexes for each tail. The indexes have been defined in linux/rcu_segcblist.h, so this commit removes the redundant definitions in kernel/rcu/tree.h.
