This function returns no indication of how many msrs it actually did set.
Should it?
It can't hurt. Is returning the number of msrs set in the return code
(ala short write) acceptable, or do I need to make this a read/write ioctl?
I'd have thought that you'd just copy the number written into msrs->nmsrs via
msrs->nmsrs = num_entries;
like kvm_dev_ioctl_set_msrs() does. Dunno...
It means making it an _IOWR() ioctl, but no matter.
