Christoph Hellwig 9c69de4c94 nfsd: remove <linux/nfsd/nfsfh.h>
The only real user of this header is fs/nfsd/nfsfh.h, so merge the
two.  Various lockѕ source files used it to indirectly get other
sunrpc or nfs headers, so fix those up.

Trond Myklebust aad56de378 lockd: Remove unnecessary BUG_ON()s in the xdr client code
- Offset bound checks are done in the NFS client code.
- So are filehandle size checks
- The cookie length is a constant
- The utsname()->nodename is already bounded

Chuck Lever bf2695516d SUNRPC: New xdr_streams XDR decoder API
Now that all client-side XDR decoder routines use xdr_streams, there
should be no need to support the legacy calling sequence [rpc_rqst *,
__be32 *, RPC res *] anywhere.  We can construct an xdr_stream in the
generic RPC code, instead of in each decoder function.

This is a refactoring change.  It should not cause different behavior.

Chuck Lever 9f06c719f4 SUNRPC: New xdr_streams XDR encoder API
Now that all client-side XDR encoder routines use xdr_streams, there
should be no need to support the legacy calling sequence [rpc_rqst *,
__be32 *, RPC arg *] anywhere.  We can construct an xdr_stream in the
generic RPC code, instead of in each encoder function.

Also, all the client-side encoder functions return 0 now, making a
return value superfluous.  Take this opportunity to convert them to
return void instead.

This is a refactoring change.  It should not cause different behavior.

Chuck Lever 3460f29a27 lockd: Introduce new-style XDR functions for NLMv4
We'd like to prevent local buffer overflows caused by malicious or
broken servers.  New xdr_stream style decoders can do that.

For efficiency, we also want to be able to pass xdr_streams from
call_encode() to all XDR encoding functions, rather than building
an xdr_stream in every XDR encoding function in the kernel.

Same idea as the NLM v3 XDR overhaul.
