H A D | kern_switch.c | diff 98469 Thu Jun 20 04:21:20 MDT 2002 peter Move the "- 1" into the RQB_FFS(mask) macro itself so that implementations can provide a base zero ffs function if they wish. This changes #define RQB_FFS(mask) (ffs64(mask)) foo = RQB_FFS(mask) - 1; to #define RQB_FFS(mask) (ffs64(mask) - 1) foo = RQB_FFS(mask); On some platforms we can get the "- 1" for free, eg: those that use the C code for ffs64().
