Subject: systat(1): vmstat: dinfo(): compute rates using real elapsed time
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=168c28e78e7655843a32f776700d8b87063224ad;p=openbsd

systat(1): vmstat: dinfo(): compute rates using real elapsed time

The "naptime" value is not the real elapsed time.  But showkre() has
the real elapsed time, "etime", so pass that as argument to dinfo().
