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.
