Nevertheless I was going to repeat the performance measurements on a
recent kernel but haven't gotten around to that yet because the
measurements need to be performed with CONFIG_PREEMPT_RT_FULL to
be reliable (a vanilla kernel is too jittery), so I have to create
a new branch with RT patches on the test machine, which is fairly
involved and time consuming.

I assume you will then mainline the changes, so you don't need to do
it again? That is the problem with doing development work on a dead
kernel.

I think the limitation is outside of his control as not all of the RT
patches are in mainline yet.
