How do I know my UBI/UBIFS code version?

How do I know my UBI/UBIFS code version?

[Woody Wu]

I am running ubi/ubifs on a ported ARM linux 3.1.x.  How do I get know my ubi/ubifs version? In additional, if I found the version are too old, could I simply copy a newer version source files to my 3.1 ARM linux tree?

Thanks in advance.

try "ubinfo -a"

I'm no expert, but UBI/UBIF probably has dependencies upon the rest of
the kernel, if the kernel API that it uses have changed then you may
have trouble copying newer files around.

Cheers,
Steve

Ported in terms of utterly broken by a SoC vendor? ;-)
If your kernel version is v3.1 then also UBI and UBIFS is v3.1 unless
someone messed with it.
To find out you need to consult the changelog.

And no, you cannot simply copy&paste the sources files between kernel
releases as the internal kernel API is
a moving target.

'ubinfo -a' returns to me "UBI version: 1" in its first line output.  Does it looks strange to you?  Thanks.

This version is always 1.
If we consider UBI Fastmap at some point rock stable _and_ make it default we'll change this version maybe to 2.

So, back to my original question, how do I know my UBI version? Just '1' in the case?  Thanks.
