Hi all,

This is the latest 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, shrink, nfs handles, verity, or
any other feature that could make use of quickly deriving an inodes path from
the mount point.  

This set can be viewed on github here
https://github.com/allisonhenderson/xfs/tree/xfs_new_pptrsv10

And the corresponding xfsprogs code is here
https://github.com/allisonhenderson/xfsprogs/tree/xfsprogs_new_pptrs_v10

This set has been tested with the below parent pointers tests
https://lore.kernel.org/fstests/20221012013812.82161-1-catherine.hoang@oracle.com/T/#t

Updates since v9:

Reordered patches 2 and 3 to be 6 and 7

xfs: Add xfs_verify_pptr
   moved parent pointer validators to xfs_parent

xfs: Add parent pointer ioctl
   Extra validation checks for fs id
   added missing release for the inode
   use GFP_KERNEL flags for malloc/realloc
   reworked ioctl to use pptr listenty and flex array

NEW
   xfs: don't remove the attr fork when parent pointers are enabled

NEW
   directory lookups should return diroffsets too

NEW
   xfs: move/add parent pointer validators to xfs_parent

Questions comments and feedback appreciated!

Thanks all!
Allison
