What you are looking for is very much the lttng-ust tracer. It outputs
CTF traces from an instrumented userspace program (and allows to
instrument the said program). The info about this tracer is available at
http://lttng.org/lttng2.0. There are no packages currently for
lttng-ust, but the git tree can be used:

git://git.lttng.org/lttng-ust.git

in combination with lttng-tools and liburcu.

Best regards,

Mathieu
