Damn, I just found a use for this in lguest.
Any chance of handing "next" to the sched_out hook so we can optimize the lguest <-> lguest switch?
FYI, lguest turns off PGE globally when you load the module, because turning it off on each guest entry v. slow. With these hooks I can be far smarter...
Thanks! Rusty.
