Subject: [for-next][PATCH 4/5] tracing: Make hash-ptr option default
Date: Mon, 15 Feb 2021 14:55:37 -0500 [thread overview]
Message-ID: <20210215195558.150797411@goodmis.org> (raw)
In-Reply-To: 20210215195533.101751000@goodmis.org
From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>
Since the original behavior of the trace events is to hash the %p pointers,
make that the default, and have developers have to enable the option in
order to have them unhashed.
