Subject: [5/5] doc: rcu: Update description of gp_seq fields in rcu_data
Date: Tue, 25 Sep 2018 11:26:01 -0700 [thread overview]
Message-ID: <20180925182601.37421-6-joel@joelfernandes.org> (raw)
In-Reply-To: <20180925182601.37421-1-joel@joelfernandes.org>
The rcu_state structure doesn't have a gp_seq_needed field. Update the
description under rcu_data accordingly, to reflect this.
