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, 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_pptrsv6

And the corresponding xfsprogs code is here
https://github.com/allisonhenderson/xfsprogs/tree/xfsprogs_new_pptrs_v6

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 v5:

xfs: Increase XFS_QM_TRANS_MAXDQS to 5
  NEW
xfs: parent pointer attribute creation
  Declare xfs_create_space_res,  xfs_mkdir_space_res static
xfs: add parent attributes to link
  Declare xfs_link_space_res static
xfs: add parent attributes to symlink
  Declare xfs_symlink_space_res static
xfs: remove parent pointers in unlink
  Declare xfs_remove_space_res static
xfs: Add parent pointers to rename
  Declare xfs_rename_space_res static
xfs: Add parent pointer ioctl 
  Added out_unlock goto

Questions comments and feedback appreciated!

Thanks all!
Allison
