LTTng driver submission for inclusion in staging

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I hereby propose the LTTng kernel tracer for inclusion into the staging
area of the Linux kernel. For those eager to try it out, and to get
information about the features of this tracer, you should grab the
control/consumer/viewer tools at: http://lttng.org/lttng2.0

Feedback is very welcome!
