Subject: [PATCH tip/core/rcu 07/12] rcu: Inline rcu_kthread_do_work() into its sole remaining caller
Date: Wed, 9 Jan 2019 13:18:45 -0800 [thread overview]
Message-ID: <20190109211850.31599-7-paulmck@linux.ibm.com> (raw)
In-Reply-To: <20190109211830.GA30595@linux.ibm.com>
The rcu_kthread_do_work() function has a single-line body and only one
remaining caller. This commit therefore saves a few lines of code by
inlining rcu_kthread_do_work() into its sole remaining caller.
