2008-10-31net: replace NIPQUAD() in net/*/Harvey Harrison
Using NIPQUAD() with NIPQUAD_FMT, %d.%d.%d.%d or %u.%u.%u.%u can be replaced with %pI4 Signed-off-by: Harvey Harrison <harvey.harrison@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-10-10RPC/RDMA: correct the reconnect timer backoffTom Talpey
The RPC/RDMA code had a constant 5-second reconnect backoff, and always performed it, even when re-establishing a connection to a server after the RPC layer closed it due to being idle. Make it an geometric backoff (up to 30 seconds), and don't delay idle reconnect. Signed-off-by: Tom Talpey <talpey@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2008-10-10RPC/RDMA: adhere to protocol for unpadded client trailing write chunks.Tom Talpey
The RPC/RDMA protocol allows clients and servers to avoid RDMA operations for data which is purely the result of XDR padding. On the client, automatically insert the necessary padding for such server replies, and optionally don't marshal such chunks.

2008-10-10RPC/RDMA: suppress retransmit on RPC/RDMA clients.Tom Talpey
An RPC/RDMA client cannot retransmit on an unbroken connection, doing so violates its flow control with the server. Signed-off-by: Tom Talpey <talpey@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2008-10-10RPC/RDMA: support FRMR client memory registration.Tom Talpey
Configure, detect and use "fastreg" support from IB/iWARP verbs layer to perform RPC/RDMA memory registration. Make FRMR the default memreg mode (will fall back if not supported by the selected RDMA adapter). This allows full and optimal operation over the cxgb3 adapter, and others.

2008-03-07SUNRPC: Fix a nfs4 over rdma transport oopsTom Talpey
Prevent an RPC oops when freeing a dynamically allocated RDMA buffer, used in certain special-case large metadata operations. Signed-off-by: Tom Talpey <tmt@netapp.com> Signed-off-by: James Lentini <jlentini@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2008-01-30SUNRPC: Clean up functions that free address_strings arrayChuck Lever
Clean up: document the rule (kfree) and the exceptions (RPC_DISPLAY_PROTO and RPC_DISPLAY_NETID) when freeing the objects in a transport's address_strings array. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2008-01-30SUNRPC: Add support for per-client timeout valuesTrond Myklebust
In order to be able to support setting the timeo and retrans parameters on a per-mountpoint basis, we move the rpc_timeout structure into the rpc_clnt. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2008-01-30SUNRPC: Rename xprt_disconnect()Trond Myklebust
xprt_disconnect() should really only be called when the transport shutdown is completed, and it is time to wake up any pending tasks. Rename it to xprt_disconnect_done() in order to reflect the semantical change. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2007-11-26SUNRPC: remove NFS/RDMA client's binary sysctlsJames Lentini
Support for binary sysctls is being deprecated in 2.6.24. Since there are no applications using the NFS/RDMA client's binary sysctls, it makes sense to remove them. The patch below does this while leaving the /proc/sys interface unchanged. Please consider this for 2.6.24.
