Can anyone confirm if sysinfo:::pswitch/sysinfo::preempt:inv_swtch fires 
'before' or 'after' the context switch?  

I know sched:::off-cpu fires before the context switch, but not quite sure 
about sysinfo:::pswitch and sysinfo::preempt:inv_swtch.If these fire after the 
context switch, is there any way to use sched:::off-cpu and still be able to 
distinguish between voluntary and involuntary context switches?

Thanks,
Neelam
