sched: Ensure a task has a non-normalized vruntime when returning back to CFS
Current code ensures that a task has a normalized vruntime when switching away from the fair class, but it does not ensure the task has a non-normalized vruntime when switching back to the fair class. This is an example breaking this consistency: 1. a task is in fair class and !queued 2. changes its class to RT class (still !queued) 3. changes its class to fair class again (still !queued) Signed-off-by: Byungchul Park <> Signed-off-by: Peter Zijlstra (Intel) <> Cc: Linus Torvalds <> Cc: Mike Galbraith <> Cc: Peter Zijlstra <> Cc: Thomas Gleixner <> Link: Signed-off-by: Ingo Molnar <>
