Subject: [PATCH tip/core/rcu 13/13] rcu: Remove rcu_user_hooks_switch
Date: Tue, 23 Feb 2016 21:12:50 -0800 [thread overview]
Message-ID: <1456290770-18659-13-git-send-email-paulmck@linux.vnet.ibm.com> (raw)
In-Reply-To: <20160224051221.GA17099@linux.vnet.ibm.com>
From: Yang Shi <yang.shi@linaro.org>
Because there are neither uses nor intended uses for the
rcu_user_hooks_switch() function that was orginally intended
for nohz use, this commit removes it.
