At the moment the wrong buffer head's data is being unescaped. To test this case mount a filesystem with data=journal, start creating and deleting a bunch of files containing only JFS_MAGIC_NUMBER (0xc03b3998), then pull the plug on the device. Without this patch the files will contain zeros instead of the correct data after recovery.
