Subject: [PATCH 1/2] rcu: declare rcu_eqs_special_set() in public header
Date: Sun, 25 Mar 2018 20:50:03 +0300 [thread overview]
Message-ID: <20180325175004.28162-2-ynorov@caviumnetworks.com> (raw)
In-Reply-To: <20180325175004.28162-1-ynorov@caviumnetworks.com>
rcu_eqs_special_set() is declared only in internal header
kernel/rcu/tree.h and stubbed in include/linux/rcutiny.h.
This patch declares rcu_eqs_special_set() in include/linux/rcutree.h, so
it can be used in non-rcu kernel code.
