JFFS2: Releases? Versions?

JFFS2: Releases? Versions?

[Bernhard Priewasser]

Hi all,

i have just a simple question about JFFS2 & versioning. Too simple 
perhaps... please be patient with me...

I'm confused about the version numbers of JFFS2, "JFFS2 version 2.2. 
(NAND)" (out of a dmesg / boot) for example.

If source code + CVS available: How can i determine the release version?
If source code available: How can i determine the release version?
How can i determine the release of JFFS2 currently running in a kernel?
Is there some changelog "overview" (not only for single files)?

I have to start evaluating (or rather analyzing...) JFFS2 on different 
platforms and flash chips, and it's hard to distinguish between the 
releases already running on some devices here.

Best Thanks & Regards,
Bernhard

Those version numbers are very infrequently updated. We started at 2.0,
then updated to 2.1 in the very early days when we had to change the
format. Then the version number remained unchanged for a long time until
the NAND support was added and it was increased to 2.2.

The 2.4 kernel has JFFS2 2.1, and the 2.6 kernel has JFFS2 2.2. These
are the jffs2-2_4-branch and the HEAD of the CVS tree, respectively.

There isn't really an overall 'version' other than the one described
above, which isn't particularly useful. You can look at the $Id$ tags in
the files though, which will indicate the date on which the snapshot was
taken, if they're using a snapshot from CVS instead of whatever was
present in the kernel they started with.

Thank God JFFS2 itself does work better than its versioning :)
