From: Darrick J. Wong <djwong@xxxxxxxxxx> Source kernel commit: a26dc21309af68623b82b4e366cbbeb5a85ce65b Once we've assembled all the parent pointers for a file, we need to are embedded in the xattr structure, which means that we must write a new extended attribute structure, again, atomically. Therefore, we must copy the non-parent-pointer attributes from the file being repaired into the temporary file's extended attributes and then call the atomic extent swap mechanism to exchange the blocks.
