If you switch the cgroup of a sleeping thread, its vruntime does not get adjusted correctly for the difference between the min_vruntime values of the two groups. This patch adds a new callback, prep_move_task, to struct sched_class to give sched_fair the opportunity to adjust the task's vruntime just before setting its new group. This allows us to properly normalize a sleeping task's vruntime when moving it between different cgroups.
