Any review done is useful anyway ;)

Either Eric or me will take the patch, but in the past such fixes have
sometimes also been taken into the net tree; honestly I wouldn't mind a
bit more "rule" here as it's a bit weird that some of our patches are Cc
to fsdevel@ (fs/ from fs/9p) and the other half netdev@ (net/ from
net/9p), but afaict the MAINTAINERS syntax doesn't have a way of
excluding e.g. net/9p from the `NETWORKING [GENERAL]` group so I guess
we just have to live with that.

There's little enough volume and netdev automation sends a mail when a
patch is picked up, so as long as there's no conflict (large majority of
the cases) such fixes can go either way as far as I'm concerned.
