They're having no trouble that I'm aware of, and I definitely would be
made aware. They're not currently using a kernel with NO_HZ_FULL even
built in, as that stuff is far far too raw in the current kernel.
They may meet a NO_HZ_FULL enabled kernel soonish, but will be told to
not turn it on for anything other than pure compute, as NO_HZ_FULL is
currently not usable for mixed load in partitioned box, much less rt.
