The following lttng patch is necessary to have the tracing hooks in the kernel.
The following ltt-control module controls the tracing.
** NOTE : RPM and debian packages are only made once a version has been
thoroughly tested. If they do not exist at the moment, please install from
sources (see section 2 below). To see the list of compatibilities between

You might also want to have libncurses5 to have the text mode kernel
configuration menu, but there are alternatives.
