Name:xas_next() - Move state to next index.*@xas: XArray operation state.* If the @xas was in an error state, it will remain in an error state* and this function will return %NULL. If the @xas has never been walked,

Proto:static inline void *xas_next(struct xa_state *xas)

Type:void

Parameter:

TypeParameterName
struct xa_state *xas
1774  node = xa_node
1776  If Value for the false possibility is greater at compile time(True if the pointer is something other than a node || Bits remaining in each slot || xa_offset == XA_CHUNK_MASK) Then Return __xas_next() - Find the next entry in the XArray.*@xas: XArray operation state.* Helper function for xas_next() which handles all the complex cases* out of line.

page_cache_next_misspage_cache_next_miss() - Find the next gap in the page cache.*@mapping: Mapping.*@index: Index.*@max_scan: Maximum range to search.* Search the range [index, min(index + max_scan - 1, ULONG_MAX)] for the* gap with the lowest index.
find_get_pages_contigd_get_pages_contig - gang contiguous pagecache lookup*@mapping: The address_space to search*@index: The starting page index*@nr_pages: The maximum number of pages*@pages: Where the resulting pages are placed* find_get_pages_contig() works exactly like
add_to_swap_cacheadd_to_swap_cache resembles add_to_page_cache_locked on swapper_space,* but sets SwapCache flag and private instead of mapping and index.
__delete_from_swap_cacheThis must be called only on pages that have* been verified to be in the swap cache.
migrate_page_move_mappingReplace the page in the mapping.* The number of remaining references must be:* 1 for anonymous pages without a mapping* 2 for pages with a mapping* 3 for pages with a mapping and PagePrivate/PagePrivate2 set.
