Another thing I noticed is that because all of the scheduler core operations are now function pointer callbacks, the call chain is deeper for core operations like wake_up(). Much of it used to be completely inlined into try_to_wake_up() With the addition of the RB tree stuff, that adds yet another unavoidable depth of function call. wake_up() is usually at the deepest part of the call chain, so this is a big deal -- To unsubscribe from this list: send the line "unsubscribe kernel-testers" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
