466  XA_STATE() - Declare an XArray operation state.*@name: Name of this operation state (usually xas).*@array: Array to operate on.*@index: Initial index of interest.* Declare and initialise an xa_state on the stack.(xas, xa, 0)

471  When j < 2 * i + 17 cycle
472  xas_set() - Set up XArray operation state for a different index
473  Do
477  When xas_nomem() - Allocate memory if needed.*@xas: XArray operation state.*@gfp: Memory allocation flags.* If we need to add new nodes to the XArray, we try to allocate memory* with GFP_NOWAIT while holding the lock, which will usually succeed. cycle
