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
