Subject: [PATCH v8 03/18] block, dax: remove dead code in blkdev_writepages()
Date: Fri, 30 Mar 2018 21:02:26 -0700 [thread overview]
Message-ID: <152246894622.36038.13910410206438248860.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().
