| xas_store | xas_store() - Store this entry in the XArray |
| __xas_prev | __xas_prev() - Find the previous entry in the XArray.*@xas: XArray operation state.* Helper function for xas_prev() which handles all the complex cases* out of line. |
| __xas_next | __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. |
| xas_find | xas_find() - Find the next present entry in the XArray |
| xa_load | xa_load() - Load an entry from an XArray.*@xa: XArray.*@index: index into array.* Context: Any context. Takes and releases the RCU lock.* Return: The entry at @index in @xa. |
| __xa_cmpxchg | __xa_cmpxchg() - Store this entry in the XArray |
| __xa_insert | __xa_insert() - Store this entry in the XArray if no entry is present.*@xa: XArray.*@index: Index into array.*@entry: New entry.*@gfp: Memory allocation flags.* Inserting a NULL entry will store a reserved entry (like xa_reserve())* if no entry is present |
| __xa_set_mark | __xa_set_mark() - Set this mark on this entry while locked.*@xa: XArray.*@index: Index of entry.*@mark: Mark number.* Attempting to set a mark on a %NULL entry does not succeed.* Context: Any context. Expects xa_lock to be held on entry. |
| __xa_clear_mark | __xa_clear_mark() - Clear this mark on this entry while locked.*@xa: XArray.*@index: Index of entry.*@mark: Mark number.* Context: Any context. Expects xa_lock to be held on entry. |
| ida_free | da_free() - Release an allocated ID.*@ida: IDA handle.*@id: Previously allocated ID.* Context: Any context. |
| check_xa_mark_2 | |
| check_xa_shrink | |
| check_account | Check that the pointer / value / sibling entries are accounted the* way we expect them to be. |
| find_get_entry | d_get_entry - find and get a page cache entry*@mapping: the address_space to search*@offset: the page cache index* Looks up the page cache slot at @mapping & @offset |
| find_get_pages_contig | d_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 |
| __test_set_page_writeback | |
| __clear_shadow_entry | Regular page slots are stabilized by the page lock even without the tree* itself locked. These unlocked entries need verification under the tree* lock. |
| migrate_page_move_mapping | Replace 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. |
| migrate_huge_page_move_mapping | The expected number of remaining references is the same as that* of migrate_page_move_mapping(). |
| split_huge_page_to_list | This function splits huge page into normal pages. @page can point to any* subpage of huge page to split. Split doesn't change the position of @page.* Only caller must hold pin on the @page, otherwise split fails with -EBUSY.* The huge page must be locked. |
| dax_insert_entry | By this point grab_mapping_entry() has ensured that we have a locked entry* of the appropriate size so we don't have to worry about downgrading PMDs to* PTEs |
| __add_to_page_cache_locked | |
| dax_lock_page | dax_lock_mapping_entry - Lock the DAX entry corresponding to a page*@page: The page whose entry we want to lock* Context: Process context.* Return: A cookie to pass to dax_unlock_page() or 0 if the entry could* not be locked. |
