Modified Files: src/sys/dev/dkwedge: dk.c Log Message: dk(4): Strengthen dkopen preconditions. This cannot be called before dkwedge_attach for the same unit returns, so sc->sc_dev is guaranteed to be set to a nonnull device_t and the state is guaranteed not to be larval. And this cannot be called concurrently with dkwedge_detach, or after dkwedge_detach does vdevgone until another wedge with the same number is attached (which can't happen until dkwedge_detach completes), so the state is guaranteed not to be dying or dead. Hence sc->sc_dev != NULL and sc->sc_state == DKW_STATE_RUNNING.
