From 49c336c1679295a31b92223dca05feccfe3e3464 Mon Sep 17 00:00:00 2001
From: David Goulet <dgoulet@efficios.com>

Subject: [PATCH] Support new lttng-ust error code
Signed-off-by: David Goulet <dgoulet@efficios.com>
---
Only keep the src/bin/lttng-sessiond/lttng-ust-error.h adding part,
needed to build lttng-tool without the lttng-libust dependency, i.e.
with --disable-lttng-ust. (Samuel Martin)
