sunrpc: add a debugfs rpc_xprt directory with an info file in it
Add a new directory heirarchy under the debugfs sunrpc/ directory: sunrpc/ rpc_xprt/ <xprt id>/ Within that directory, we can put files that give info about the xprts. We do have the (minor) problem that there is no succinct, unique identifier for rpc_xprts. So we generate them synthetically with a static atomic_t counter. For now, this directory just holds an "info" file, but we may add other files to it in the future. Signed-off-by:Jeff Layton <jlayton@primarydata.com> Signed-off-by:
