-Subject: ubifs: Add option to create UBI FS version 4 on empty UBI volume
-
-Instead of creating an ubifs file system with format version 5 by
-default on empty UBI volumes add a compile option to create an older ubi
-with file system format version 4 instated. This allows it to be mount
-as a volume on kernel versions < 4.10, which does not support format
-version 5.
-We saw that some people can not access their older data when they
-downgraded from kernel 4.14 to kernel 4.9 to prevent this this option
-would help.
