Dsplit_page_table_lock.rst14 最初，mm->page_table_lock spinlock保护了mm_struct的所有页表。但是这种方
19 PMD表使用分页锁。对高层表的访问由mm->page_table_lock保护。
38 时启用PTE表的分页表锁。如果分页锁被禁用，所有的表都由mm->page_table_lock
52 对PMD_SIZE页面采取pmd分割锁，否则mm->page_table_lock；

Dsplit_page_table_lock.rst7 Originally, mm->page_table_lock spinlock protected all page tables of the
14 tables. Access to higher level tables protected by mm->page_table_lock.
35 If split lock is disabled, all tables are guarded by mm->page_table_lock.
