Revision 0c2043abefacac97b6d01129c1123a466c95b7c1 authored by Linus Torvalds on 07 October 2007, 23:17:38 UTC, committed by Linus Torvalds on 07 October 2007, 23:23:13 UTC
It turns out that there are a few other five-second timers in the kernel, and if the timers get in sync, the load-average can get artificially inflated by events that just happen to coincide. So just offset the load average calculation it by a timer tick. Noticed by Anders Boström, for whom the coincidence started triggering on one of his machines with the JBD jiffies rounding code (JBD is one of the subsystems that also end up using a 5-second timer by default).
