From: Jérémie Galarneau Date: Fri, 28 Nov 2014 16:07:17 +0000 (-0500) Subject: Fix: Don't leave events enabled if they were saved in a disabled state X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=065321e96273c671652d316800faacf2ed20025e;p=lttng-tools.git Fix: Don't leave events enabled if they were saved in a disabled state Events are enabled by default on creation. The session configuration loader must make sure to disable them after creation when restoring an event that was saved in the "disabled" state.
