Hi everyone, Christoph and I have been working to get the directory parent pointers patchset into shape for merging in the next kernel cycle. This v13 release contains what I hope are the last ondisk format changes -- we've gone back to parent pointers being xattrs attached to the child, wherein the attr name is the dirent name, and the attr value is a handle to the parent directory. We've solved the pptr lookup uniqueness problem by forcing all XFS_ATTR_PARENT attr lookups to be done on the name and value; avoided namehash collisions on container farms by adjusting the hash function slightly; and avoided the entire log incompat feature flag mess by defining a permanent incompat feature for parent pointers and using totally separate attr log item opcodes. With that, I think this is finally ready to go.
