Subject: [RFC PATCH 59/86] treewide: rcu: remove cond_resched()
Date: Tue, 7 Nov 2023 15:07:55 -0800 [thread overview]
Message-ID: <20231107230822.371443-3-ankur.a.arora@oracle.com> (raw)
In-Reply-To: <20231107230822.371443-1-ankur.a.arora@oracle.com>
All the cond_resched() calls in the RCU interfaces here are to
drive preemption once it has reported a potentially quiescent
state, or to exit the grace period. With PREEMPTION=y that should
happen implicitly.
So we can remove these.
