The patch remove this a-priori open and open the device only when verbs are really needed. I do not think its issue at the verbs but more issue in how the librdmacm use the verbs. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
