名称	描述
follow_pmd_mask
__pte_alloc
__pte_alloc_kernel
__do_fault	The mmap_sem must have been held on entry, and may have been* released depending on flags and vma->vm_ops->fault() return value.* See filemap_fault() and __lock_page_retry().
pte_alloc_one_map
alloc_set_pte	alloc_set_pte - setup new PTE entry for given page and add reverse page* mapping
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_pte_fault	These routines also need to handle stuff like marking pages dirty* and/or accessed for architectures that don't do it in hardware (most* RISC architectures)
__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.
get_old_pmd
walk_pmd_range
vmalloc_to_page	Walk a vmap address to the struct page it maps.
vmemmap_pmd_populate
shadow_mapped
zero_pmd_populate
kasan_free_pmd
__do_huge_pmd_anonymous_page
set_huge_zero_page	Caller must hold page table lock.
do_huge_pmd_anonymous_page
insert_pfn_pmd
move_huge_pmd
collapse_huge_page
__mcopy_atomic
hmm_vma_walk_pmd
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
is_swap_pmd
pmd_none_or_clear_bad
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
