I think I might be mad to include that many mailing lists in this patchset... As I explained in [PATCH 1/5], fstests covers more and more fs testing thing, so we always get help from fs specific mailing list, due to they learn about their features and bugs more. Besides that, some folks help to review patches (relevant with them) more often. So I'd like to bring in the similar way of linux/MAINTAINERS, records fs relevant mailing lists, reviewers or supporters (or call co-maintainers). To recognize the contribution from them, and help more users to know who or what mailing list can be added in CC list of a patch. (The MAINTAINERS and get_maintainer.pl are copied from linux project, then I made some changes for fstests specially.) PATCH 3~5 are still under reviewing, hasn't been decided... About [3/5], if someone mailing list doesn't want to be in cc list of related fstests patch, please clarify, I'll remove. About [4/5], if someone people doesn't want to be CCed, tell me, I'll remove. About [5/5], need more reviewing from btrfs list. If others fs which *always send patches to fstests@* and *hope to have a specific co-maintainer* who can help more on your patches (to fststs) before merging, refer to [5/5]. Thanks, Zorro
