There is another potential update of preferred_zone in this function
after which the classzone_idx should probably be refreshed:
/*
* Find the true preferred zone if the allocation is unconstrained by
* cpusets.
*/
if (!(alloc_flags & ALLOC_CPUSET) && !nodemask)
first_zones_zonelist(zonelist, high_zoneidx, NULL,
&preferred_zone);
