McKenney" <paulmck@...ux.vnet.ibm.com> Subject: [PATCH tip/core/rcu 10/22] rcu: Declare rcu_eqs_special_set() in public header From: Yury Norov <ynorov@...iumnetworks.com> 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.
