Is this something that will work with any of the Kernels that Ubuntu Studio

"The *patch* [2] by Linux kernel developer Mike Galbraith adds a mere 233
lines of code to the kernel's scheduler, but it cuts desktop latency down by
a factor of ten. That's impressive — it's almost like getting a new
computer.  In the Linux Kernel Mailing List, *Linus Torvalds himself praised
the performance boost* [3] he gets from the patch."

...So I think this is firmly one of those "real improvement" patches. Good
job. Group scheduling goes from "useful for some specific server loads" to
"that's a killer feature"

...You wouldn't think that such a simple patch could make such a big
difference, but the proof is there. I've tried it myself and I was
impressed. You can see for it yourself in these *before- and after-the-patch
Phoronix videos* [6].
