From 4f435ebe7d0422af61cdcddbbcc659888645a1e1 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Mon, 3 Oct 2016 09:11:50 -0700 Subject: xfs: don't mix reflink and DAX mode for now Since we don't have a strategy for handling both DAX and reflink, for now we'll just prohibit both being set at the same time.
