xas_descend
xas_pausexas_pause() - Pause a walk to drop a lock.*@xas: XArray operation state.* Some users need to pause a walk and drop the lock they're holding in* order to yield to a higher priority thread or carry out an operation* on an entry
__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_findxas_find() - Find the next present entry in the XArray
xas_find_markedxas_find_marked() - Find the next marked entry in the XArray.*@xas: XArray operation state.*@max: Highest index to return.*@mark: Mark number to search for.* If the @xas has not yet been walked to an entry, return the marked entry
xas_reloadxas_reload() - Refetch an entry from the xarray
xas_next_entryxas_next_entry() - Advance iterator to next present entry.*@xas: XArray operation state.*@max: Highest index to return.* xas_next_entry() is an inline function to optimise xarray traversal for* speed

xas_prevxas_prev() - Move iterator to previous 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,
xas_nextxas_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,
