do_fault_around | do_fault_around() tries to map few pages around the fault address. The hope* is that the pages will be needed soon and this will lower the number of* faults to handle.* It uses vm_ops->map_pages() to map the pages, which skips the page if it's |
__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(). |
__follow_pte_pmd | |
pmd_none_or_clear_bad_unless_trans_huge | Used when setting automatic NUMA hinting protection where it is* critical that a numa hinting PMD is not confused with a bad PMD. |

page_vma_mapped_walk | page_vma_mapped_walk - check if @pvmw->page is mapped in @pvmw->vma at*@pvmw->address*@pvmw: pointer to struct page_vma_mapped_walk. page, vma, address and flags* must be set. pmd, pte and ptl must be NULL.* Returns true if the page is mapped in the vma |

__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. |

wp_clean_pmd_entry | wp_clean_pmd_entry - The pagewalk pmd callback. |
userfaultfd_must_wait | Verify the pagetables are still not ok after having reigstered into* the fault_pending_wqh to avoid userland having to UFFDIO_WAKE any* userfault that has already been resolved, if userfaultfd_read and* UFFDIO_COPY|ZEROPAGE are being run simultaneously on |
dax_iomap_pte_fault | |
pmd_trans_huge_lock | mmap_sem must be held on entry |
pmd_none_or_trans_huge_or_clear_bad | This function is meant to be used by sites walking pagetables with* the mmap_sem hold in read mode to protect against MADV_DONTNEED and* transhuge page faults |
