Yes, we're getting at a point where the xfs_inode size starts to
really hurt. It's all the small incrementally and very useful changes
like this series or the in-memory unlinked inode list from Dave that
keep growing it.  I have no really good answer here except that I'd
need to dust off some of my project to reduze the size by removing
fields that we don't strictly need.
