Subject: [PATCH 0/2] mm: introduce per-order mTHP split counters

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
