From: Yury Norov <[email protected]> Because rcu_eqs_special_set() is declared only in internal header kernel/rcu/tree.h and stubbed in include/linux/rcutiny.h, it is inaccessible outside of the RCU implementation. This patch therefore moves the rcu_eqs_special_set() declaration to include/linux/rcutree.h, which allows it to be used in non-rcu kernel code.
