FYI, I'd prefer to just see the series without patches 6, 7 and 9 for
now. They aren't really related to the rest, and I think this series:
http://git.infradead.org/users/hch/xfs.git/shortlog/refs/heads/xfs-kill-XLOG_STATE_IOERROR
has a better approach to sort out those areas. The rest looks really
good to me modulo minor cleanups here and there.
