Message-ID: <548DB542.7000400@gmail.com>
Date: Mon, 15 Dec 2014 00:05:22 +0800
From: Chen Gang <gang.chen.5i5j@...il.com>
To: megaraidlinux@....com, JBottomley@...allels.com,
Sumit Saxena <sumit.saxena@...gotech.com>
CC: linux-scsi@...r.kernel.org,
"linux-kernel@...r.kernel.org" <linux-kernel@...r.kernel.org>
Subject: [PATCH v2] drivers: scsi: megaraid: Add "megaraid_sas_internal.h"
for internal shared functions using
For shared inline functions crossed source files, better to let it as
"static inline" in a header file. For extern functions, better to
declare them in header file.
