|---|---|
| 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. |
