next_zones_zonelist - Returns the next zone at or below highest_zoneidx within the allowed nodemask using a cursor within a zonelist as a starting point - The cursor used as a starting point for the search - The zone index of the highest zone to return - An optional nodemask to filter the zonelist with - The first suitable zone found is returned via this parameter
This function returns the next zone at or below a given zone index that is within the allowed nodemask using a cursor as the starting point for the search. The zoneref returned is a cursor that represents the current zone being examined. It should be advanced by one before calling next_zones_zonelist again.
