Yes, and _require_scratch_dax seems to be a better choice. And I found that the "chattr +/-x" check could also pass on a dax device mounted without "-o dax".

'chattr +/-x' only works on a dax device. When checking if the 'x' attribute is supported by XFS_IO_PROG: _require_xfs_io_command "chattr" "x" (called by xfs/260) it's better to do the check on a dax device mounted with dax option.
