In the patch that adds account_guest_time(), have a CONFIG_GUEST_ACCOUNTING (defaulting to n, with no description, help, or dependencies. Then, CONFIG_KVM can select GUEST_ACCOUNTING. The advantages of this are: - the puppyvisor can also select this if it so wishes - we don't have core code reference some obscure module CONFIG_PREEMPT_NOTIFIERS does the same thing. -- Do not meddle in the internals of kernels, for they are subtle and quick to panic. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
