Subject: [RELEASE] LTTng modules 2.7.3 (Linux kernel tracer)
Date: Tue, 26 Apr 2016 20:44:12 +0000 (UTC) [thread overview]
Message-ID: <130601745.70308.1461703452927.JavaMail.zimbra@efficios.com> (raw)
Hi,
This is a bugfix release (2.7.3) of the LTTng modules Linux kernel
tracer. It mainly consists of fixing kernel instrumentation
quirks with older kernels, and adapting to some new distribution
kernels (e.g. RHEL), and adapting to the 4.6 Linux kernels.
The two issues about ctf_user_integer and lib_ring_buffer_copy_from_user_inatomic
that are fixed here are harmless, because they were unused in the code base
so far.
