The only place where we need to know the initiator is in kvm_write_tsc() which has an implicit index. At the moment yes, but it might have other uses in the future. > I have been trying to determine whether there is a possibility for taking a context switch while a guest initiated set_msr() is in progress whereby the new thread might invoke the set_msr()/kvm_write_tsc() routines. It looks to me like this is not possible but I can't be sure.
