We don't have any report field of this type yet. Return this patch into the play if we really need that. Currenly we always report status (result of "status" dm ioctl) for an LV as a whole where we choose segment which represents the LV, not calling status for each possible segment it contains - we don't need this now so I'm removing it to not make the code more complex uselessly.
