Hi all,
This is the 7th 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. This set also
introduces deferred attribute operations, though it is currently only used by
the new parent pointer code.
Some points of interest since v6:
I've integrated most of the feedback provided on v6, and addressed some bugs
I found during the log replay in patch 6. Patches 2, 7, and 21 are new, so
I would appreciate some focus on those. I'm still working on an alternate
solution to patch 3, but wanted to give folks an update for where things
are at the moment.
As always, comments and feedback are appreciated. Thank you!
