I've been thinking about this patch, and I'm not happy with it any more :-)

I want to migrate people away from using 'xip' to 'dax' without breaking
anybody's scripts.  So I'm thinking about adding a new 'dax' option and
having the 'xip' option print a warning and force-enable the 'dax' option.
That way people who might have scripts to look for 'xip' in /proc/mounts
won't break.
