Fix looks ok, but I wonder: upper fs with no xattr support is really a crippled
case we only need to support for backward compat. right?
How about pre testing the noxattr condition on mount time (on workdir)
and issue a warning at mount time along the same lines of:
pr_warn("overlayfs: upper fs needs to support d_type.\n");
pr_warn("overlayfs: upper fs does not support tmpfile.\n");
pr_warn("overlayfs: upper fs does not support xattr.\n");
