Additionally, it fixes many smaller issues in the code improving its robustness and performance. Except for supporting large (>32KB) rpc's, it addresses all known issues in the client. It's my hope this patchset can be queued for the upcoming merge window. It has been extensively tested with both IB and iWARP adapters under Connectathon and heavy parallel load. This patchset applies to the current nfs-2.6 git; (4330ed8ed4da360ac1ca14b0fddff4c05b10de16) --- Tom Talpey (14): RPC/RDMA: optionally emit useful transport info upon connect/disconnect. RPC/RDMA: reformat a debug printk to keep lines together. RPC/RDMA: harden connection logic against missing/late rdma_cm upcalls. RPC/RDMA: correct a 5 second pause on reconnecting to an idle server. RPC/RDMA: fix connect/reconnect resource leak. RPC/RDMA: return a consistent error to mount, when connect fails. RPC/RDMA: adhere to protocol for unpadded client trailing write chunks. RPC/RDMA: avoid an oops due to disconnect racing with async upcalls. RPC/RDMA: maintain the RPC task bytes-sent statistic. RPC/RDMA: suppress retransmit on RPC/RDMA clients. RPC/RDMA: support FRMR client memory registration. RPC/RDMA: check selected memory registration mode at runtime. RPC/RDMA: add data types and new FRMR memory registration enum. RPC/RDMA: refactor the inline memory registration code.
