 * and page->virtual store page management information, but all other fields
 * are unused and could be used privately, carefully. The management of this
 * page is the responsibility of the one who allocated it, and those who have
 * subsequently been given references to it.
 *
 * The other pages (we may call them "pagecache pages") are completely
 * managed by the Linux memory manager: I/O, buffers, swapping etc.
 * The following discussion applies only to them.
 *
 * A pagecache page contains an opaque `private' member, which belongs to the
 * page's address_space. Usually, this is the address of a circular list of
 * the page's disk buffers. PG_private must be set to tell the VM to call
 * into the filesystem to release these pages.
 *
 * A page may belong to an inode's memory mapping. In this case, page->mapping
 * is the pointer to the inode, and page->index is the file offset of the page,
 * in units of PAGE_SIZE.
 *
 * If pagecache pages are not associated with an inode, they are said to be
 * anonymous pages. These may become associated with the swapcache, and in that
 * case PG_swapcache is set, and page->private is an offset into the swapcache.
 *
 * In either case (swapcache or inode backed), the pagecache itself holds one
 * reference to the page. Setting PG_private should also increment the
 * refcount. The each user mapping also has a reference to the page.
 *
 * The pagecache pages are stored in a per-mapping radix tree, which is
 * rooted at mapping->i_pages, and indexed by offset.
 * Where 2.4 and early 2.6 kernels kept dirty/clean pages in per-address_space
 * lists, we instead now tag pages as dirty/writeback in the radix tree.
 *
 * All pagecache pages may be subject to I/O:
 * - inode pages may need to be read from disk,
 * - inode pages which have been modified and are MAP_SHARED may need
 *   to be written back to the inode on disk,
 * - anonymous pages (including MAP_PRIVATE file mappings) which have been
 *   modified may need to be swapped out to swap space and (later) to be read
 *   back into memory.

 *
 * Choice of value:
 *
 * By making GUP_PIN_COUNTING_BIAS a power of two, debugging of page reference
 * counts with respect to pin_user_pages() and unpin_user_page() becomes

 * counts up using the bias value. This means that the lower bits are left for
 * the exclusive use of the original code that increments and decrements by one
 * (or at least, by much smaller values than the bias value).
 *
 * Of course, once the lower bits overflow into the upper bits (and this is

 * Calculate the expected folio refcount, taking references from the pagecache,

 * combination with folio_ref_count() to detect unexpected references (e.g.,
 * GUP or other temporary references).
 *
 * Does currently not consider references from the LRU cache. If the folio
 * was isolated from the LRU (which is the case during migration or split),
 * the LRU cache does not apply.
 *
 * Calling this function on an unmapped folio -- !folio_mapped() -- that is
 * locked will return a stable result.
 *
 * Calling this function on a mapped folio will not result in a stable result,
 * because nothing stops additional page table mappings from coming (e.g.,
 * fork()) or going (e.g., munmap()).
 *
 * Calling this function without the folio lock will also not result in a
 * stable result: for example, the folio might get dropped from the swapcache
 * concurrently.
 *
 * However, even when called without the folio lock or on a mapped folio,
 * this function can be used to detect unexpected references early (for example,
 * if it makes sense to even lock the folio and unmap it).
 *
 * The caller must add any reference (e.g., from folio_try_get()) it might be
 * holding itself to the result.
