jffs-dev@axis.com is practically dead.  Iirc, the list was used for
the old jffs[1] code.  Jffs2 is usually discussed on
linux-mtd@lists.infradead.org (added to Cc:).

Patch looks sane.  Does it still apply against dwmw2's latest tree?
http://git.infradead.org/?p=mtd-2.6.git

[ Patch kept for the benefit of linux-mtd ]

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 linux-mtd@lists.infradead.org would seem to make sense
though.
