Subject: [PATCH 35/57] perf tools: Remove unused trace_find_next_event()
Date: Mon, 21 Oct 2019 10:38:12 -0300 [thread overview]
Message-ID: <20191021133834.25998-36-acme@kernel.org> (raw)
In-Reply-To: <20191021133834.25998-1-acme@kernel.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.
