The main purpose of this series is to address more connection drop recovery issues by fixing FRMR re-use to make it less likely the client will drop the connection due to a memory operation error. Some other clean-ups and fixes are present as well. See topic branch nfs-rdma-for-3.17 in git://git.linux-nfs.org/projects/cel/cel-2.6.git I tested with NFSv3 and NFSv4 on all three supported memory registration modes. Used cthon04 and iozone with both Solaris and Linux NFS/RDMA servers. Used xfstests with Linux. --- Chuck Lever (13): xprtrdma: Fix panic in rpcrdma_register_frmr_external() xprtrdma: Protect ->qp during FRMR deregistration xprtrdma: Limit data payload size for ALLPHYSICAL xprtrdma: Update rkeys after transport reconnect xprtrdma: Don't drain CQs on transport disconnect xprtrdma: Unclutter struct rpcrdma_mr_seg xprtrdma: Encode Work Request opcode in wc->wr_id xprtrdma: Back off rkey when FAST_REG_MR fails xprtrdma: Refactor rpcrdma_buffer_put() xprtrdma: Release FRMR segment buffers during LOCAL_INV completion xprtrdma: Clean up rpcrdma_ep_disconnect() xprtrdma: Remove RPCRDMA_PERSISTENT_REGISTRATION macro xprtrdma: Handle additional connection events include/linux/sunrpc/xprtrdma.h | 2 net/sunrpc/xprtrdma/rpc_rdma.c | 77 +++++---- net/sunrpc/xprtrdma/transport.c | 17 +- net/sunrpc/xprtrdma/verbs.c | 330 +++++++++++++++++++++++++++------------ net/sunrpc/xprtrdma/xprt_rdma.h | 63 ++++++- 5 files changed, 332 insertions(+), 157 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
