The only special check in find_busiest_group() helping MT/MC balancing
is pwr_now and pwr_move calculations..
What about the very messy code I had to put in so that
find_busiest_group() would return a group even if there were no queues
in the group with more than one task. Similar for find_busiest_queue().
Thats messy for sure and that was introduced by you to fix an imabalance
issue for a simple DP system(with out breaking HT systems). I will post a fix
for that.
By moving the active load balance trigger out of load_balance() and
providing an independent trigger that does not require sub optimal
normal load balancing, I hope?
