[Xen Developer <developerxen@xxxxxxxxx>]

Hello  :)

i reading function csched_acct() in algorithm Credit. i two problem in code:

1- what mean's Variable credit_peak,credit_balance,credit_xtra, credit_fair? What is the difference?

2- The following code, Why should weight_total be gathered and then divided?

        if ( prv->credit_balance < 0 )

        {

            credit_peak += ( ( -prv->credit_balance

                               * sdom->weight

                               * sdom->active_vcpu_count) +

                             (weight_total - 1)

                           ) / weight_total;

        }
