From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: Ross Zwisler To: Toshi Kani , Mike Snitzer , dm-devel@redhat.com Cc: linux-fsdevel@vger.kernel.org, linux-kernel@vger.kernel.org, linux-nvdimm@lists.01.org, Ross Zwisler Subject: [PATCH 7/7] dm-error: remove unnecessary direct_access() stub Date: Thu, 24 May 2018 20:55:18 -0600 Message-Id: <20180525025518.11405-8-ross.zwisler@linux.intel.com> In-Reply-To: <20180525025518.11405-1-ross.zwisler@linux.intel.com> References: <20180525025518.11405-1-ross.zwisler@linux.intel.com> Sender: linux-kernel-owner@vger.kernel.org List-ID: 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.
