Subject: Re: [PATCH v3 tip/core/rcu 0/6] Dynticks updates for 4.11
Date: Tue, 24 Jan 2017 13:46:02 -0800 [thread overview]
Message-ID: <20170124214602.GA2269@linux.vnet.ibm.com> (raw)
In-Reply-To: <20170118024456.GA2042@linux.vnet.ibm.com>
Hello!
This series provides v3 of the dynticks updates:
1-4. Abstract access to the dyntick counter, replacing the current
open-coding of atomic operations.
5. Check cond_resched_rcu_qs() state less often to reduce GP overhead.
6. Adjust FQS offline checks for exact online-CPU detection.
Changes since v2:
o Fix RCU_TRACE() statements called out by Josh Triplett.
Changes since v1:
o Apply feedback from Josh Triplett and Peter Zijlstra.
Thanx, Paul
