Subject: pr_stats.c: Don't use an array for tot_jiffies variable
X-Git-Tag: v11.7.1~43
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=624374b9caea3a5c164c138662973b867f423995;p=sysstat

pr_stats.c: Don't use an array for tot_jiffies variable

We don't need 3 variables, only 2 are enough.
