Reviewing is a good way to gain knowledge of the codebase, though. Even
if the reviews weren't very thorough in the beginning, I'd still be
willing to pay that price if the new reviewer was going to stay around
for a longer time. (When you said "I'd propose to do it", you probably
didn't mean becoming a long-term reviewer, but I thought I should make
this point anyway.)

Are there any patches in the set that you'd be comfortable if I tagged
them with "Reviewed-by: Anton Lundin <glance at acc.umu.se>"?

Well, I don't really have a checklist in my mind when doing reviews,
but there's one point that gets easily forgotten by people who write
patches (and sometimes I also forget to check it when reviewing): the
commit message should clearly explain why the change is made, what
problem it tries to solve.

Regarding the code itself, I read the changes and try to understand why
each individual change is done. If I can't understand, I'll ask for
clarification. While figuring out how the code works, I may get ideas
about how to do it better, or weird formatting or "bad" naming may
irritate enough for me to complain. Also, I try all the time to think
of ways how the code may break - maybe a pointer dereference isn't
always safe, or maybe allocated resources aren't always freed properly

Yes, it is.

Indeed, that may be a better alternative than keeping the patches
waiting for review indefinitely.
