Hello :)
I'm seeing "iostat -x -k 1" print this after a RAID1 rebuild on 4.0-rc5.
It's not abnormal other than it's 3-disk, with one being SSD (sdc) and
the other two being write-mostly:

This was working on 3.18. Shall I bisect, or is it obvious?
It seems to just be leaking as the counters were going up gradually while
it was rebuilding.
