2008-01-30SUNRPC: Clean up functions that free address_strings arrayChuck Lever1-6/+10
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 Myklebust1-1/+1
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: Fix an unnecessary implicit type cast in rpcrdma_count_chunks()Chuck Lever1-1/+1
Nit: rl_nchunks is an unsigned integer, so pass it into rpcrdma_count_chunks() via an unsigned integer argument. This eliminates a harmless mixed sign comparison in rpcrdma_count_chunks() Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Cc: Thomas Talpey <Thomas.Talpey@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2008-01-30SUNRPC: Prevent mixed sign comparisons in rpcrdma_convert_iovs()Chuck Lever1-3/+3
Keep the type of the buffer position the same during iovec conversion to reduce the likelihood of unexpected results from comparisons and length computations.

2008-01-30SUNRPC: Rename xprt_disconnect()Trond Myklebust1-2/+2
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>

2007-12-12SUNRPC xprtrdma: fix XDR tail buf marshalling for all opsJames Lentini1-8/+1
rpcrdma_convert_iovs is passed an xdr_buf representing either an RPC request or an RPC reply. In the case of a request, several calculations and tests involving pos are unnecessary. In the case of a reply, several calculations and tests involving pos are incorrect (the code tests pos against the reply xdr buf's len field, which is always 0 at the time rpcrdma_convert_iovs is executed). This change removes the incorrect/unnecessary calculations and tests involving pos. This fixes an observed problem when reading certain file sizes over NFS/RDMA.

2007-11-27SUNRPC: remove NFS/RDMA client's binary sysctlsJames Lentini1-5/+5
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.
