Hi all,
This is the 6th 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 v5:
Patches 2 and 14 are new, so I would appreciate some focus on those.
They lay the ground work for delaying transaction rolls until
the entire operation is finished. Patches 15 through 18 have been
adjusted to hold locks across create, link, remove and rename operations.
Corresponding userspace and test cases are enroute.
As always, comments and feedback are appreciated. Thank you!
