Subject: [PATCH v2 07/15] tools lib traceevent: Optimize pretty_print() function
Date: Thu, 02 Jul 2020 14:53:51 -0400
Message-ID: <20200702185704.559785000@goodmis.org> (raw)
In-Reply-To: <20200702185344.913492689@goodmis.org>

From: "Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>

Each time the pretty_print() function is called to print an event,
the event's format string is parsed. As this format string does not
change, this parsing can be done only once - when the event struct
is initialized.
