 For printing flags bitfields as a collection of symbolic constants that
 would construct the value. The type of flags is given by the third
-character. Currently supported are [p]age flags, [v]ma_flags (both
-expect ``unsigned long *``) and [g]fp_flags (expects ``gfp_t *``). The flag
-names and print order depends on the particular        type.
