[HPDD-discuss] [PATCH 3/3] lustre: lov: Drop rq_buflen field

The rq_buflen field of the lov_request structure is never initialized. It is only used in the free of req->rq_oi.oi_md in lov_finish_set. But no oi_md field is ever initialized to the result of calling OBD_ALLOC_LARGE. So it seems that the call to OBD_FREE_LARGE in lov_finish_set and the rq_buflen in the lov_request structure are simply not needed.
