Change Details

- Don't add 1 to the result of DOMAINSET_FLS(). It uses 1-indexing already. - If a domainset consists entirely of empty domains, return true without modifying the set. Otherwise it is impossible to use DOMAINSET_FIXED reliably in kernel code. - Always flatten a _PREFER policy to _ROUNDROBIN if the preferred domain is empty. Previously we were doing this only when ds_cnt > 1.
