Hi everyone, This deluge contains all of the additions to the parent pointers patchset that I've been working since last month's deluge. The kernel and xfsprogs patchsets are based on Allison's v10 tag from last week; the fstests patches are merely a part of my development tree. To recap Allison's cover letter: "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." v10r1d2 rebases everything against 6.3-rc2. I still want to remove the diroffset from the ondisk parent pointer, but for v10 I've replaced the sha512 hashing code with modifications to the xattr code to support lookups based on name *and* value. With that working, we can encode parent pointers like this: (parent_ino, parent_gen, name[]) xattr lookups still work correctly, and repair doesn't have to deal with keeping the diroffsets in sync if the directory gets rebuilt. With this change applied, I'm ready to weave my new changes into Allison's v10 and call parent pointers done. :) The online directory and parent pointer code are exactly the same as the v9r2d1 release, so I'm eliding that and everything that was in Allison's recent v10 patchset. IOWs, this deluge includes only the bug fixes I've made to parent pointers, the updates I've made to the ondisk format, and the necessary changes to fstests to get everything to pass.

Or, if you want me to merge my ondisk format changes into my branches, I'll put out v11 with everything taken care of. --D
