Hi David and Ryan, Thanks for taking time to review! Updated the doc. How about the following? split is incremented every time a huge page is successfully split into smaller orders. This can happen for a variety of reasons but a common reason is that a huge page is old and is being reclaimed. split_failed is incremented if kernel fails to split huge page. This can happen if the page was pinned by somebody. split_deferred is incremented when a huge page is put onto split queue. This happens when a huge page is partially unmapped and splitting it would free up some memory. Pages on split queue are going to be split under memory pressure, if splitting is possible. Thanks, Lance
