Hi all, This is the latest rebase of parent pointer attributes for xfs. The goal of this patch set is to add a parent pointer attribute to each inode. The attribute name containing the parent inode, generation, and directory offset, while the attribute value contains the file name. This feature will enable future optimizations for online scrub, or any other feature that could make use of quickly deriving an inodes path from the mount point. It's been quite a while since we've seen parent pointers, so I think I'm just going to start the versioning back at 1 rather than continue as v30 of the giant extended set. Questions comments and feedback appreciated! Thanks all!
