From: Darrick J. Wong <djwong@xxxxxxxxxx> Once we've assembled all the parent pointers for a file, we need to commit the new dataset atomically to that file. Parent pointer records 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.
