This makes no sense. If you want to override MINPHYS, you need to override for the whole kernel, not only here. > @@ -157,6 +158,8 @@ vioblk_minphys(struct buf *bp, struct scsi_link *sl) > struct vioblk_softc *sc = sl->adapter_softc; > if (bp->b_bcount > sc->sc_xfer_max) > bp->b_bcount = sc->sc_xfer_max; > + if (bp->b_bcount > MINPHYS) > + bp->b_bcount = MINPHYS; This is useless. sc->sc_xfer_max is computed so that it will always be <= MINPHYS.
