LTTng, the Linux Trace Toolkit Next Generation, is a project that aims at
producing a highly efficient full system tracing solution.  It is composed of
several components to allow tracing of the kernel, of userspace, trace viewing
and analysis and trace streaming.  LTTng is open source software. It is being
actively developed with the community.


LTTng 0.243 removes the NMI-safe page fault for x86_64, which causes problems on
some setups. vmalloc_sync_all() called after buffer allocation and after module
load ensures that no vmalloc faults are triggered by LTTng from NMI context.

lttng-modules 0.19.6 fixes uninitialized fields in net-extended events.
