Hi Doug, This series was posted a month ago. If you have any comments, I would appreciate if you could please post them. Otherwise, could we please push this series to v4.5? If you need, I can rebase it over your for-4.5 branch once you'll open such a branch. Thanks, Matan -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
