Hi Linus, These are the proposed RDMA patches for 5.4 This cycle has proved to be quiet with a focus on bug fix and cleanup style patches, and less on major new functionality. I am aware of no conflicts. The following changes since commit f74c2bb98776e2de508f4d607cd519873065118e: Linux 5.3-rc8 (2019-09-08 13:33:15 -0700) 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 3eca7fc2d8d1275d9cf0c709f0937becbfcf6d96: RDMA: Fix double-free in srq creation error flow (2019-09-16 14:37:38 -0300) ---------------------------------------------------------------- RDMA subsystem updates for 5.4 This cycle mainly saw lots of bug fixes and clean up code across the core code and several drivers, few new functional changes were made. - Many cleanup and bug fixes for hns - Various small bug fixes and cleanups in hfi1, mlx5, usnic, qed, bnxt_re, efa - Share the query_port code between all the iWarp drivers - General rework and cleanup of the ODP MR umem code to fit better with the mmu notifier get/put scheme - Support rdma netlink in non init_net name spaces - mlx5 support for XRC devx and DC ODP ---------------------------------------------------------------- Andrey Konovalov (1): RDMA/mlx4: Untag user pointers in mlx4_get_umem_mr Arnd Bergmann (1):
