SUNRPC xptrdma: simplify build configuration
Trond and Bruce,
This is a patch for 2.6.25. This is the same version that was sent out
on December 12 for review (no comments to date).
To simplify the RPC/RDMA client and server build configuration, make
SUNRPC_XPRT_RDMA a hidden config option that continues to depend on
SUNRPC and INFINIBAND. The value of SUNRPC_XPRT_RDMA will be:
- N if either SUNRPC or INFINIBAND are N
- M if both SUNRPC and INFINIBAND are on (M or Y) and at least one is M
- Y if both SUNRPC and INFINIBAND are Y
In 2.6.25, all of the RPC/RDMA related files are grouped in
net/sunrpc/xprtrdma and the net/sunrpc/xprtrdma/Makefile builds both
the client and server RPC/RDMA support using this config option.
