Both of these patches assume that user space has a special
configuration that works together with the non-standard driver
behavior.

For this reason, I suggest making the new driver behavior optional,
with the default being the origin version that "just works".  In that
way, the admin/user can choose the special configuration on purpose,
and the default performance will not be degraded.

Thanks,
