31 * - An 'owner' is a &struct drm_master that is not leasing objects from
32 * another &struct drm_master, and hence 'owns' the objects. The owner can be
33 * identified as the &struct drm_master for which &drm_master.lessor is NULL.
35 * - A 'lessor' is a &struct drm_master which is leasing objects to one or more
36 * other &struct drm_master. Currently, lessees are not allowed to
39 * - A 'lessee' is a &struct drm_master which is leasing objects from some

42 * it is leasing in &drm_master.leases.
