Hi, Those are bugfix releases of the stable 2.9 and 2.10 branches of the LTTng-UST project. The most notable fix is the one regarding alignment of ring buffer shm space reservation, which may cause LTTng-UST channels to fail to be created for large number of sub-buffers.
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.
