From 41ef7b00abff4d31814890a14e5a8e49a177508b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Alex=20Benn=C3=A9e?= Date: Fri, 1 Aug 2014 17:08:56 +0100 Subject: trace: teach lttng backend to use format strings MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This makes the UST backend pay attention to the format string arguments that are defined when defining payload data.
