    [PATCH] "io wait" process accounting · 7b88e5e0
    Andrew Morton authored
    Patch from Rik adds "I/O wait" statistics to /proc/stat.
    
    This allows us to determine how much system time is being spent
    awaiting IO completion.  This is an important statistic, as it tends to
    directly subtract from job completion time.
    
    procps-2.0.9 is OK with this, but doesn't report it.
