Subject: [RELEASE] LTTng-modules 2.9.11, 2.10.8, 2.11.0-rc2 (Linux kernel tracer)
Date: Thu, 1 Nov 2018 18:56:22 -0400 (EDT) [thread overview]
Message-ID: <60988959.4070.1541112982406.JavaMail.zimbra@efficios.com> (raw)
Hi,
This is a set of bugfix releases of the LTTng modules kernel tracer.
It covers the three currently active lttng-modules branches: the
2.9 and 2.10 stable branches, as well as the 2.11 branch in release
candidate cycle.
Those releases add support for kernel 4.19.
One important improvement is to prevent allocation of buffers larger
than the available memory, which can cause the OOM killer to trigger.
Even if the OOM killer end up having to trigger, the current OOM kill
target is set to the current thread while allocating buffers.
Enjoy!
Mathieu
