[lttng-dev] [RELEASE] LTTng-modules 2.9.13, 2.10.10, 2.11.0-rc5 (Linux kernel tracer)

[Mathieu Desnoyers]

Hi,

These releases to the LTTng 2.9 and 2.10 stable branches, as well
as the release candidate for the LTTng 2.11 branch, contain a
series of bugfixes, and adds support for the 5.1 and 5.2-rc Linux
kernels.

One user-impacting fix is the following:

"Fix: don't access packet header for stream_id and stream_instance_id getters"

which can cause the consumer daemon to get an erroneous value of
stream ID and stream instance ID (0) when a live timer is fired at
the beginning of the buffer lifetime. This affects users of the live
streaming mode.
