Most cases yes. If it doesn't apply nicely all the way back, then I
expect an email report from someone telling me that their stable
backport failed to apply cleanly. And if I get time, I try to fix it.

Well, any bug that can cause an oops I like to get backported. Tracing
is a different beast than most of the kernel. There's 1000s of options
one can do, and some of these bugs only trigger if you apply one of
those 1000s of options. Thus, it may go unnotice for years, but all it
takes is to be debugging your subsystem in an old kernel using the
tracing infrastructure, and you happen to stumble on one of these bugs
(that I decided not to backport because it's been what? 3 years?) and
the system crashes due to the tracing system. That person will be
pretty pissed and not trust tracing. So yeah, I do backport them.
I also maintain the stable -rt kernel releases. 8 of them to be exact,
and they range from 3.2-rt to 4.4-rt. I like to have these up to date
with the latest tracing fixes too.
