Hi all,
This is the 9th version 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.
Some points of interest since v8:
I've integrated the feed back from v8 and reworked the xfs_parent_add routine
in patch 20 which is used in the corresponding xfsprogs set. I try to push all
three sets at once since sometimes changes in one set can affect the others.
Most of the activity this time is in xfsprogs and xfstests. So feedback
there appreciated! As usual folks are welcome to go through any part of it, but
I know it's a lot. Thanks again everyone!
Allison
