This passes xfs tests in the following configurations: 1) MKFS_OPTIONS="-m reflink=0" MOUNT_OPTIONS="-o dax" 2) MKFS_OPTIONS="-m reflink=0" but with the added configuration step of setting the dax attribute on the mounted test directory. I also tested to ensure that reflink fails when a file has the dax attribute set. I've got more testing to do, but figured I'd at least let you know I've been looking at it. Thanks! Jeff
