[PATCH] Fix strange size check in __get_vm_area_node()
Recently, __get_vm_area_node() was changed like following
if (unlikely(!area))
return NULL;
- if (unlikely(!size)) {
- kfree (area);
+ if (unlikely(!size))
return NULL;
- }
It is leaking `area', also original code seems strange already.
Probably, we wanted to do this patch.
