名称	描述
copy_pmd_range
zap_pmd_range
__handle_mm_fault	By the time we get here, we already hold the mm semaphore* The mmap_sem may have been released depending on flags and our* return value. See filemap_fault() and __lock_page_or_retry().
change_pmd_range
move_page_tables
__pmd_trans_huge_lock	Returns page table lock pointer if a given pmd maps a thp, NULL otherwise.* Note that if it returns page table lock pointer, this routine returns without* unlocking page table lock. So callers must unlock it.
get_mctgt_type_thp	We don't consider PMD mapped swapping or file mapped pages because THP does* not support them for now.* Caller should make sure that pmd_trans_huge(pmd) is true.
pmd_trans_huge_lock	mmap_sem must be held on entry
