From 0b9547bf6b94317b3f8e2496dc2b44cb6e599b01 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Tue, 27 Mar 2018 10:51:22 -0400 Subject: 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 Signed-off-by: J.
