WARN seems a little high for this. xfs_notice() or xfs_info() would
seem more appropriate:
#define KERN_WARNING KERN_SOH "4" /* warning conditions */
#define KERN_NOTICE KERN_SOH "5" /* normal but significant condition */
#define KERN_INFO KERN_SOH "6" /* informational */

Nope, warning level is correct and consistent with what we've used
for these experimental warnings.
xfs_warn(mp, "DAX enabled. Warning: EXPERIMENTAL, use at your own risk");
i.e. A message that says "Expect things not to work correctly in
your filesystem" is definitely worth warning level meddaging.
