From: Jérémie Galarneau Date: Tue, 8 Mar 2016 03:35:23 +0000 (-0500) Subject: lttng enable-channel memsets lttng_channel to -1 X-Git-Url: http://git.efficios.com/?p=lttng-tools.git;a=commitdiff_plain;h=394ff38e77d4510a4ff806eb187bf739e84561c6 lttng enable-channel memsets lttng_channel to -1 The lttng enable-channel command uses a global struct lttng_channel which it initializes to contain all "-1". This is a hack used to set tag all attributes as "unset" which has the unfortunate consequence of setting the extended pointer to a non-sensical value. This workaround explicitly sets the extended pointer to NULL, but this command should be refactored so it is no longer necessary.
