extended using growfs(8). The problem here is that geom_label checks if the filesystem size recorded in UFS superblock is equal to the provider (i.e. device) size. This check cannot be removed due to backward compatibility. On the other hand, in most cases growfs(8) cannot set fs_size in the superblock to match the provider size, because, differently from newfs(8), it cannot recompute cylinder group sizes. To fix this problem, add another superblock field, fs_providersize, used only for this purpose. The geom_label(4) will attach if either fs_size (filesystem created with newfs(8)) or fs_providersize (filesystem expanded using growfs(8)) matches the device size.
