Do I smell a bug when a task switches its scheduling classes?
Lets say a task was in real-time class for a long time and switches to fair-sched class. When update_curr() is called on this new fair-sched task, some of required fields (for ex: exec_start) are uninitialized and can lead to bogus calculations?
Also, real-time tasks are currently influencing fair clock calculations (because there is only one raw_weighted_load field per runqueue). Is that intentional?
