Hi, LTTng-UST 2.11.4 and 2.12.2 are bug fix releases of the LTTng-UST user-space tracer for the 2.11 and 2.12 stable branches. There are a few fixes, as well as a in-depth rework of the benchmark code which was sitting in the tests of lttng-ust. This test code was contributed more than 10 years ago before I took maintainership of the LTTng-UST project, and it was in a broken state (always returned 0 second on my test machine because it was truncating significant digits). So I reworked the benchmark in the 2.11 and 2.12 stable branches to facilitate comparison of benchmarks between branches, especially given the major rework done in the upcoming 2.13 version.
