Subject: [PATCH rcu 18/26] rcu: Rename rcu_dynticks_zero_in_eqs() into rcu_watching_zero_in_eqs()
Date: Fri, 16 Aug 2024 09:32:33 +0530 [thread overview]
Message-ID: <20240816040241.17776-18-neeraj.upadhyay@kernel.org> (raw)
In-Reply-To: <20240816040030.GA16986@neeraj.linux>
From: Valentin Schneider <vschneid@redhat.com>
The context_tracking.state RCU_DYNTICKS subvariable has been renamed to
RCU_WATCHING, reflect that change in the related helpers.
