Hi all,
At present, the split counters in THP statistics no longer include
PTE-mapped mTHP. Therefore, we want to introduce per-order mTHP split
counters to monitor the frequency of mTHP splits. This will assist
developers in better analyzing and optimizing system performance.
/sys/kernel/mm/transparent_hugepage/hugepages-<size>/stats
split_page
split_page_failed
deferred_split_page
Thanks,
Lance

mm: add per-order mTHP split counters
mm: add docs for per-order mTHP split counters

We really have to start documenting these, and what the sementics are.
E.g., is split_page_failed contained in split_page? Is
deferred_split_page contained in split_page?
But also: just don't call it "split_page". Drop the "_page".
split
split_failed
split_deferred
?
