Subject: [PATCH v3 [resend] 17/18] smp: rename call_single_queue as call_function_queue
Date: Mon, 16 Dec 2013 00:36:39 +0800	[thread overview]
Message-ID: <1387125400-28849-18-git-send-email-liuj97@gmail.com> (raw)
In-Reply-To: <1387125400-28849-1-git-send-email-liuj97@gmail.com>

From: Jiang Liu <jiang.liu@huawei.com>

Now the same list is used to serve both single and multiple function
call requests, so rename call_single_queue as call_function_queue.
