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!
Allison
