--- Comment #2 from Jonathan Lebon <jlebon at redhat dot com> ---
Added support for TRACE_SYSTEM in branch jlebon/trace_system:
$ stap -l 'kernel.trace("*")' | head
kernel.trace("9p:9p_client_req")
kernel.trace("9p:9p_client_res")
kernel.trace("9p:9p_protocol_dump")
kernel.trace("asoc:snd_soc_bias_level_done")
kernel.trace("asoc:snd_soc_bias_level_start")
kernel.trace("asoc:snd_soc_cache_sync")
kernel.trace("asoc:snd_soc_dapm_connected")
kernel.trace("asoc:snd_soc_dapm_done")
kernel.trace("asoc:snd_soc_dapm_input_path")
kernel.trace("asoc:snd_soc_dapm_output_path")
$ stap -e 'probe kernel.trace("sched:sched_switch") { println($$system, ":",
$$name); exit() }'
sched:sched_switch
$
The old syntax is of course still supported. Because this change breaks the
value returned by pn(), the --compatible=2.6 switch can be used to disable
TRACE_SYSTEM support.
