--- Comment #39 from Chris Wilson <chris at chris-wilson.co.uk> ---
The discussion here has petered out, away from the io_schedule_timeout being
the issue, and we are still debating the merits of the global iowait as being a
valid statistic. (Note that customers probably want to watch blockstats instead
if they want to track an overloaded block device.)
