Subject: [PATCH 2/2] perf: Remove unused trace_find_next_event()
Date: Thu, 17 Oct 2019 17:05:23 -0400	[thread overview]
Message-ID: <20191017210636.224045576@goodmis.org> (raw)
In-Reply-To: 20191017210521.465613686@goodmis.org

From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>

trace_find_next_event() was buggy and pretty much a useless helper. As there
are no more users, just remove it.
