Subject: [PATCH v6 03/15] block, dax: remove dead code in blkdev_writepages()
Date: Thu, 15 Mar 2018 08:51:39 -0700 [thread overview]
Message-ID: <152112909958.24669.12976603063031646917.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)

Block device inodes never have S_DAX set, so kill the check for DAX and
diversion to dax_writeback_mapping_range().
