sunrpc: Re-purpose trace_svc_process
Currently, trace_svc_process has two call sites: 1. Just after a call to svc_send. svc_send already invokes trace_svc_send with the same arguments just before returning 2. Just before a call to svc_drop. svc_drop already invokes trace_svc_drop with the same arguments just after it is called Therefore trace_svc_process does not provide any additional information not already provided by these other trace points. However, it would be useful to record the incoming RPC procedure. So reuse trace_svc_process for this purpose. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J.
