If we treat conf->devlist more like a 2 dimensional array, we can get the devlist for a particular zone simply by indexing that array, so we don't need to store the pointers to subarrays in strip_zone. This makes strip_zone smaller and so (hopefully) searches faster. Signed-of-by: NeilBrown <neilb@suse.de>
