I take a lot of trivial fixes. I found two that I accepted that were from
umn.edu, and both of them (after a second review) were legitimate fixes.
One was in Greg's revert patch series, which I asked him to not revert, and
the other was me looking at all patches I've received with a Cc to umn.edu
emails, and was from a gmail account (which I'm assuming was someone that
was part of this group).
I have no problem with taking a trivial patch if they are really fixing a
bug. I think what needs to be done here is look at the patches that got in
that were buggy, and see why they got in.
Perhaps the answer is to scrutinize trivial patches more. To me, the only
"trivial" patch is a comment fix, or update to documentation. And even
then, I spend time reviewing it.
If you don't have time to review a patch, then by all means, don't accept
it. Perhaps the answer is simply have a higher bar on what you do accept.
There are a few people that I will accept patches from with out review. But
anyone else, I scrutinize the code before taking it in.
