Why not make it return int?
The same reason below.

If __next_local_node_mem_range() returned int, this would be easier:
+#define for_each_local_node_mem_range(i, nid, p_start, p_end, p_nid) \
+ for (i = -1;

Yes, we can do it like this.
But I tried to do something similar to for_each_free_mem_range and
for_each_free_mem_range_reverse to keep the code coincident.
How do you think to change all this similar functions into your way ?

static inline in a header file perhaps?
OK, will put it in a header file in the next version.
Thanks. :)
