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.
