Subject: [PATCH 2/4] fs: Introduce devpath_to_name()
Date: Mon,  4 Dec 2017 07:37:24 -0800	[thread overview]
Message-ID: <20171204153726.11479-3-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20171204153726.11479-1-andrew.smirnov@gmail.com>

Add a simple function to simplify the task of accepting both full path
in "/dev" and just device name as a parameter.
