* wasting some space this way, but it's much nicer than looping around
* trying to reserve each and every page size.
*
- * However, since size calculation will produce page-aligned sizes, it
- * makes sense to first try and see if we can reserve the entire memzone
- * in one contiguous chunk as well (otherwise we might end up wasting a
- * 1G page on a 10MB memzone). If we fail to get enough contiguous
- * memory, then we'll go and reserve space page-by-page.
+ * If we fail to get enough contiguous memory, then we'll go and
+ * reserve space in smaller chunks.
*
* We also have to take into account the fact that memory that we're
* going to allocate from can belong to an externally allocated memory
