It went like the following. * Beefing up preempt_notifier() results in too many different notifiers. They better be unified. * Unified notifiers are ugly (macro bonanza as expected) and cmwq hooks are always enabled unlike other notifiers. Let's just keep it simple and specialized. So, the cmwq stuff is now mostly hard coded into scheduler. For cmwq, everything is fine but it would still be great if the various notifiers can be assimilated in prettier way.
