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.
