Message-Id: <1328513548-19786-3-git-send-email-ying.huang@intel.com>
Date: Mon, 6 Feb 2012 15:32:25 +0800
From: Huang Ying <ying.huang@...el.com>
To: Alan Stern <stern@...land.harvard.edu>
Cc: ming.m.lin@...el.com, linux-kernel@...r.kernel.org,

Huang Ying <ying.huang@...el.com>
Subject: [RFC 2/5] scsi, pm, rename scsi_autopm_get/put_xxx to scsi_autopm_get/put_xxx_sync
To distinguish with the asynchronous version we will add later.
