10 With split page table lock we have separate per-table lock to serialize
11 access to the table. At the moment we use split lock for PTE and PMD
42 If split lock is disabled, all tables are guarded by mm->page_table_lock.

50 Hugetlb can support several page sizes. We use split lock only for PMD
56 takes pmd split lock for PMD_SIZE page, mm->page_table_lock
