521 * The main difference with get_user_pages() is that this function will
522 * unconditionally call handle_mm_fault() which will in turn perform all the
523 * necessary SW fixup of the dirty and young bits in the PTE, while
524 * handle_mm_fault() only guarantees to update these in the struct page.

568 * get_user_pages() - pin user pages in memory
569 * @tsk: the task_struct to use for page fault accounting, or
570 * NULL if faults are not to be recorded.
571 * @mm: mm_struct of target mm
572 * @start: starting user address
573 * @nr_pages: number of pages from start to pin
574 * @write: whether pages will be written to by the caller
575 * @force: whether to force access even when user mapping is currently
576 * protected (but never forces write access to shared mapping).
577 * @pages: array that receives pointers to the pages pinned.
578 * Should be at least nr_pages long. Or NULL, if caller
579 * only intends to ensure the pages are faulted in.
580 * @vmas: array of pointers to vmas corresponding to each page.
581 * Or NULL if the caller does not require them.
582 *
583 * Returns number of pages pinned. This may be fewer than the number
584 * requested. If nr_pages is 0 or negative, returns 0. If no pages
585 * were pinned, returns -errno. Each page returned must be released
586 * with a put_page() call when it is finished with. vmas will only
587 * remain valid while mmap_sem is held.
588 *
589 * Must be called with mmap_sem held for read or write.
590 *
591 * get_user_pages walks a process's page tables and takes a reference to
592 * each struct page that each user address corresponds to at a given
593 * instant. That is, it takes the page that would be accessed if a user
594 * thread accesses the given user virtual address at that instant.
595 *
596 * This does not guarantee that the page exists in the user mappings when
597 * get_user_pages returns, and there may even be a completely different
598 * page there in some cases (eg. if mmapped pagecache has been invalidated
599 * and subsequently re faulted). However it does guarantee that the page
600 * won't be freed completely. And mostly callers simply care that the page
601 * contains data that was valid *at some point in time*. Typically, an IO
602 * or similar operation cannot guarantee anything stronger anyway because
603 * locks can't be held over the syscall boundary.
604 *
605 * If write=0, the page must not be written to. If the page is written to,
606 * set_page_dirty (or set_page_dirty_lock, as appropriate) must be called
607 * after the page is finished with, and before put_page is called.
608 *
609 * get_user_pages is typically used for fewer-copy IO operations, to get a
610 * handle on the memory by some means other than accesses via the user virtual
611 * addresses. The pages may be submitted for DMA to devices or accessed via
612 * their kernel linear mapping (via the kmap APIs). Care should be taken to
613 * use the correct cache flushing APIs.
