Subject: [PATCH tip/core/rcu 3/4] srcu: Make process_srcu() be static
Date: Mon, 24 Jul 2017 15:15:30 -0700 [thread overview]
Message-ID: <1500934531-15333-3-git-send-email-paulmck@linux.vnet.ibm.com> (raw)
In-Reply-To: <20170724221511.GA15085@linux.vnet.ibm.com>
The function process_srcu() is not invoked outside of srcutree.c, so
this commit makes it static and drops the EXPORT_SYMBOL_GPL().
