I'm fine either way, if you don't want to split it send a commit ID for the first patch on mlx5-next. Thanks, Jason

From: Leon Romanovsky <leonro@mellanox.com> Hi, This series extend ODP to work with SRQ and XRC. Being both per-operation (e.g. RDMA write, RDMA read and atomic) and per-transport (e.g. RC, UD and XRC), we extend IB/core and mlx5 driver to provide needed information to user space.
