It seems to me that it could be useful to have a library of common virtual = time code (entirely separate from pv_ops), to avoid re-implementing some = apparently common requirements, such as: handling TSC frequency changes, = stolen time accounting, synthetic programmable clockevent etc. - James -- = James Morris
