IMO, the best solution is for drivers to cycle through qpn space before attempting to re-use any. Otherwise, this problem is more likely to occur. I can't easily think of a great alternative. - Sean -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
