Unrealistic. We are in a constant state of development, the direction of which
is determined by who is hacking on what, when - as opposed to "we need this
feature or fix now so lets direct all our efforts to that". Unfortunately the
SMP balancing changes need more than one iteration of a mainline kernel
before being incorporated due to the potential for regression so the
likelihood of "SMP nice" becoming part of mainline if it is based on this new
code is going to be (at a guess) 6 months. Of course my patch could go into
mainline in its current form and the SMP balancing code in -mm could be
modified with that in place rather than the other way around but I just
didn't get in early enough for that to happen ;)

Cheers,
Con
