Re: [PATCH v3 0/9] virtio-console: notify about the terminal size

[Filip Hejsek <filip.hejsek@gmail.com>]

I have found this 3 year old patch adding virtio console resize
support, which seems to have been forgotten at that time. I would like
to see this feature merged.

Szymon, you have originally submitted this patch, would you be willing
to update it for the latest development tree and resubmit it?

If it turns out that Szymon doesn't want to work on this anymore for
any reason (or doesn't respond), could I resubmit the patch myself?
The contributing guidelines don't say anything about this. I'm
especially unsure how to deal with Signed-off-by, as in such case I
would be (re)submitting sombody else's work, but potentially with my
modifications. I'm willing to update and test the patch, and if
necessary, address any review feedback.
