No, RFC does not say "do not merge" or "this has dependencies". RFC is
used to invite a stronger review when introducing a new concept. Its
fair game to apply patches marked RFC if maintainer is okay with the
content.

Dependencies are either noted in cover-letter or below the patch
tear-line. With what you are asking, looks like patches need to be
resubmitted once dependencies are cleared, even if there is no change in
the content itself. This will be additional work.

That said, if it makes life convenient for you, you can impose such a
rule for patches you need to handle. But I think it will take some
getting used for developers who send patches to you as I don't think
this is a norm elsewhere.

Adding Tony and Arnd as well, in case I have missed some recently
accepted convention.

Thanks,
