The values of PROCPS_SORT_ASCEND & PROCPS_SORT_DESCEND were a tad unintuitive. This patch will just make them a more natural +1 for ascending and -1 for descending. [ plus it still allows that fast path multiplication ] [ instead of a comparison for signed numbers/strings ] Signed-off-by: Jim Warner <james.warner@comcast.net>
