Several important client-side performance and scalability improvements are made in this series, proposed for the 4.3 kernel, including: - Increase maximum RPC/RDMA credits to 128 - Increase maximum NFS/RDMA r/wsize to one megabyte - Prefer inline rather than reply chunk replies And these fixes: - Send NFSv4 WRITE compounds correctly - Support RDMA_NOMSG calls - Remove support for RDMA_MSGP calls - Fix large NFS symlink operations - Get inline threshold accounting right Also available in the "nfs-rdma-for-4.3" topic branch of this git repo: git://git.linux-nfs.org/projects/cel/cel-2.6.git Or for browsing: http://git.linux-nfs.org/?p=cel/cel-2.6.git;a=log;h=refs/heads/nfs-rdma-for-4.3 Changes since v3: - Rebased on Linux v4.2-rc5 - Added v2 of Devesh's reboot crash fix - Clarified description of NFSv4 WRITE fix Changes since v2: - Rebased on Linux v4.2-rc3 - Corrected RPCRDMA_MAX_IOVS macro - Included patch to remove core ib_reg_phys_mr() API Changes since v1: - Rebased on Linux v4.2-rc2 - PHYSICAL registration, being insecure, must now be explicitly selected - Further clean-ups were done because ib_reg_phys_mr() is gone - Support for RDMA_MSGP type calls has been removed - Some patch descriptions have been clarified --- Chuck Lever (15): xprtrdma: Make xprt_setup_rdma() agnostic to family of server address xprtrdma: Raise maximum payload size to one megabyte xprtrdma: Increase default credit limit xprtrdma: Don't fall back to PHYSICAL memory registration xprtrdma: Remove last ib_reg_phys_mr() call site xprtrdma: Clean up rpcrdma_ia_open() xprtrdma: Remove logic that constructs RDMA_MSGP type calls xprtrdma: Account for RPC/RDMA header size when deciding to inline xprtrdma: Always provide a write list when sending NFS READ xprtrdma: Don't provide a reply chunk when expecting a short reply xprtrdma: Fix XDR tail buffer marshalling xprtrdma: Fix large NFS SYMLINK calls xprtrdma: Clean up xprt_rdma_print_stats() xprtrdma: Count RDMA_NOMSG type calls core: Remove the ib_reg_phys_mr() and ib_rereg_phys_mr() verbs Devesh Sharma (1): xprtrdma: take HCA driver refcount at client drivers/infiniband/core/verbs.c | 67 ---------- fs/nfs/nfs3xdr.c | 1 fs/nfs/nfs4xdr.c | 4 - include/linux/sunrpc/xprtrdma.h | 2 include/rdma/ib_verbs.h | 46 ------- net/sunrpc/xprtrdma/fmr_ops.c | 19 +++ net/sunrpc/xprtrdma/frwr_ops.c | 5 + net/sunrpc/xprtrdma/physical_ops.c | 25 ++++ net/sunrpc/xprtrdma/rpc_rdma.c | 197 +++++++++++++++--------------- net/sunrpc/xprtrdma/transport.c | 77 +++++------- net/sunrpc/xprtrdma/verbs.c | 238 +++++++++++++----------------------- net/sunrpc/xprtrdma/xprt_rdma.h | 27 ++-- 12 files changed, 285 insertions(+), 423 deletions(-) -- Chuck Lever -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
