Subject: [PATCH v3 tip/core/rcu 22/40] srcu: Add grace-period sequence numbers
Date: Wed, 19 Apr 2017 09:58:19 -0700 [thread overview]
Message-ID: <1492621117-13939-22-git-send-email-paulmck@linux.vnet.ibm.com> (raw)
In-Reply-To: <20170419165805.GB10874@linux.vnet.ibm.com>
This commit adds grace-period sequence numbers, which will be used to
handle mid-boot grace periods and per-CPU callback lists.
