    Long answer, my previous experiments with set_next_buddy showed that the
    gang groups were getting lesser cpu bandwidth than the baseline. Then I
    thought of having a new helper(set_gang_buddy) that would give better
    chance to gang sched tasks. This will only be affecting the following
    cpus. In the cpu, which has gang_leader set, the code is not giving
    undue advantage to the gang task.
