Subject: [PATCH v2 net-next 02/10] perf: remove unused __addr variable
Date: Wed, 6 Apr 2016 18:43:23 -0700 [thread overview]
Message-ID: <1459993411-2754735-3-git-send-email-ast@fb.com> (raw)
In-Reply-To: <1459993411-2754735-1-git-send-email-ast@fb.com>
now all calls to perf_trace_buf_submit() pass 0 as 4th
argument which will be repurposed in the next patch which will
change the meaning of 1st arg of perf_tp_event() to event_type
