Hi Linus, These are the proposed RDMA patches for 5.6. A very quiet cycle with few notable changes. Mostly the usual list of one or two patches to drivers changing something that isn't quite rc worthy. The subsystem seems to be seeing a larger number of rework and cleanup style patches right now, I feel that several vendors are prepping their drivers for new silicon. Thanks, Jason The following changes since commit b2dfc6765e45a3154800333234e4952b5412d792: net/rds: Use prefetch for On-Demand-Paging MR (2020-01-18 11:48:19 +0200) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma.git tags/for-linus for you to fetch changes up to 8889f6fa35884d09f24734e10fea0c9ddcbc6429: RDMA/core: Make the entire API tree static (2020-01-30 16:28:52 -0400) ---------------------------------------------------------------- RDMA subsystem updates for 5.6 - Driver updates and cleanup for qedr, bnxt_re, hns, siw, mlx5, mlx4, rxe, i40iw - Larger series doing cleanup and rework for hns and hfi1. - Some general reworking of the CM code to make it a little more understandable - Unify the different code paths connected to the uverbs FD scheme - New UAPI ioctls conversions for get context and get async fd - Trace points for CQ and CM portions of the RDMA stack - mlx5 driver support for virtio-net formatted rings as RDMA raw ethernet QPs -
