Now we can fix up the last few places that use the "xprt->stream" variable, and get rid of it from the rpc_xprt structure. Test-plan: Destructive testing (unplugging the network temporarily). Connectathon with UDP and TCP. Signed-off-by: NChuck Lever <cel@netapp.com> Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

Add a generic mechanism for skipping over transport-specific headers when constructing an RPC request. This removes another "xprt->stream" dependency. Test-plan: Write-intensive workload on a single mount point (try both UDP and TCP). Signed-off-by: NChuck Lever <cel@netapp.com> Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

Split the RPC client's main socket write path into a TCP version and a UDP version to eliminate another dependency on the "xprt->stream" variable. Compiler optimization removes unneeded code from xs_sendpages, as this function is now called with some constant arguments. We can now cleanly perform transport protocol-specific return code testing and error recovery in each path. Test-plan: Millions of fsx operations. Performance characterization such as "sio" or "iozone". Examine oprofile results for any changes before and after this patch is applied.

Create separate connection worker functions for managing UDP and TCP transport sockets. This eliminates several dependencies on "xprt->stream". Test-plan: Destructive testing (unplugging the network temporarily). Connectathon with v2, v3, and v4.

Split the socket write space callback function into a TCP version and UDP version, eliminating one dependence on the "xprt->stream" variable. Keep the common pieces of this path in xprt.c so other transports can use it too. Test-plan: Write-intensive workload on a single mount point.

Clean-up: change some comments to reflect the realities of the new RPC transport switch mechanism. Get rid of unused xprt_receive() prototype. Also, organize function prototypes in xprt.h by usage and scope. Test-plan: Compile kernel with CONFIG_NFS enabled.

Clean-up: remove only reference to xprt->pending from the socket transport implementation. This makes a cleaner interface for other transport implementations as well.

Reduce stack utilization of the RPC socket transport's send path. A couple of unlikely()s are added to ensure the compiler places the tail processing at the end of the csect.

Introduce block header comments and a function naming convention to the socket transport implementation. Provide a debug setting for transports that is separate from RPCDBG_XPRT. Eliminate xprt_default_timeout(). Provide block comments for exposed interfaces in xprt.c, and eliminate the useless obvious comments. Convert printk's to dprintk's.
