5 Originally, mm->page_table_lock spinlock protected all page tables of the
7 multi-threaded applications due high contention on the lock. To improve
10 With split page table lock we have separate per-table lock to serialize
12 tables. Access to higher level tables protected by mm->page_table_lock.

53 Hugetlb-specific helpers:
55  - huge_pte_lock()

69 allocation: slab uses page->slab_cache for its pages.

90 page->ptl is used to access split page table lock, where 'page' is struct
91 page of page containing the table. It shares storage with page->private
97  - if spinlock_t fits into long, we use page->ptr as spinlock, so we
99  - if size of spinlock_t is bigger then size of long, we use page->ptl as
