LTTng-UST, the Linux Trace Toolkit Next Generation Userspace Tracer,
is a low-overhead application tracer. The library "liblttng-ust" enables
tracing of applications and libraries.

Now that the 2.9 release of lttng-ust is out, lttng-ust 2.7.5 marks the end
of life of the stable-2.7 lttng-ust release branch. This version only adds
bugfixes.
