Subject: [PATCH] net: missing call of trace_napi_poll in busy_poll_stop
Date: Fri, 25 Aug 2017 15:04:32 +0200	[thread overview]
Message-ID: <150366627224.16965.12554507587831320156.stgit@firesoul> (raw)

Noticed that busy_poll_stop() also invoke the drivers napi->poll()
function pointer, but didn't have an associated call to trace_napi_poll()
like all other call sites.
