NAME
       cpupri_find - find the best (lowest-pri) CPU in the system

SYNOPSIS
       int cpupri_find(struct cpupri * cp, struct task_struct * p,
		       struct cpumask * lowest_mask);

ARGUMENTS
       cp
	   The cpupri context

       p
	   The task

       lowest_mask
	   A mask to fill in with selected CPUs (or NULL)

NOTE
       This function returns the recommended CPUs as calculated during the
       current invocation. By the time the call returns, the CPUs may have in
       fact changed priorities any number of times. While not ideal, it is not
       an issue of correctness since the normal rebalancer logic will correct
       any discrepancies created by racing against the uncertainty of the
       current priority configuration.

RETURNS
       (int)bool - CPUs were found
