[Xen-devel] Macro CSCHED_STAT_CRANK(_X)

[Adel Amani <adel11242000@xxxxxxxxx>]

Hello

in algorithm credit usage macro CSCHED_STAT_CRANK(_X).

i track 'perfc_incr()' and found its definition. But i don't  know usage this, for example in function csched_acct(void* dummy):

if ( prv->credit_balance < 0 )

    {

        credit_total -= prv->credit_balance;

        CSCHED_STAT_CRANK(acct_ balance);

    }

i don't means CSCHED_STAT_CRANK(acct_ balance); :(

============================== =======================

#define CSCHED_STAT_CRANK(_X)               (perfc_incr(_X))

#define perfc_incr(x)     (++this_cpu(perfcounters)[ PERFC_ ## x])
