Subject: [PATCH resend 7/7] dm-error: remove unnecessary direct_access() stub
Date:   Fri, 25 May 2018 16:00:55 -0600
Message-Id: <20180525220055.18920-8-ross.zwisler@linux.intel.com>
In-Reply-To: <20180525220055.18920-1-ross.zwisler@linux.intel.com>
References: <20180525220055.18920-1-ross.zwisler@linux.intel.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This stub was added so that we could use dm-error with
DM_TYPE_DAX_BIO_BASED mode devices.  That mode and the transition issues
associated with it no longer exist, so we can remove this dead code.
