I see that Andrew also got tired of such printk warnings, so his
fix is now in the kernel.org tree ... here's a resend of this
patch, updated against today's GIT by removing two of the printk
warning fixes.

The other three printk watning fixes don't seem to apply any more
either. I've committed the __init and __exit bits though. Thanks.

[email protected] is practically dead. Iirc, the list was used for
the old jffs[1] code. Jffs2 is usually discussed on
[email protected] (added to Cc:).

Patch looks sane. Does it still apply against dwmw2's latest tree?

Then it's overdue for the MAINTAINERS file to be updated ... it
seems wrong that the official "where to go" listing for JFFS2
points at a black hole.

Ouch! Yes, you are correct.

Can you send a patch to dwmw2?

dwmw2 is still subscribed to jffs-dev and responds... when the
moderators eventually approve non-subscriber posts, at least :)

Changing it to [email protected] would seem to make sense
though.

I'm getting section warnings with RC5 building JFFS2 as an x86 module;
the ZLIB compressors it seems.

You might want to push those __init and __exit bits soon ...
