Ok, the relevant section now looks like
+/* Returns the first zone at or below highest_zoneidx in a zonelist */
+static inline struct zone **first_zones_zonelist(struct zonelist *zonelist,
+ enum zone_type highest_zoneidx)
+{
+ struct zone **z;
+
+ for (z = zonelist->zones;
+ zone_idx(*z) > highest_zoneidx;
+ z++)
+ ;
+
+ return z;
+}
+
+/* Returns the next zone at or below highest_zoneidx in a zonelist */
+static inline struct zone **next_zones_zonelist(struct zone **z,
+ enum zone_type highest_zoneidx)
+{
+ /* Advance to the next zone in the zonelist */
+ z++;
+
+ /* Find the next suitable zone to use for the allocation */
+ for (; zone_idx(*z) > highest_zoneidx; z++)
+ ;
+
+ return z;
+}
Is that better?
