When we added hot_replace we doubled the number of devices that could be in a RAID1 array. So we doubled how far read_balance would search. Unfortunately we didn't double the point at which it looped back to the beginning - so it effectively loops over all non-replacement disks twice. This doesn't cause bad behaviour, but it pointless and means we never read from replacement devices. Signed-off-by: NeilBrown <neilb@suse.de>
