OK, thanks, I suggest using b4 relay in the future.

For authorship, both tested and review are implied. You cannot send code
which you do not think is correct, therefore your authorship fulfills
entire Reviewer's statement of oversight. There is nothing new said in
statement of oversight comparing to what authorship says.

Now for testing, I think it is also kind of obvious that whenever we can
test our own code, we test it.

For sending other people patches, we could disagree. I stand that I
would not ever send incorrect patch intentionally. Therefore reviewer's
statement of oversight is entirely redundant as well. I just cannot send
someone's patch without reviewing, thus without adhering to points
expressed by statement of oversight.

Yes, every. This applies to mass-maintainers, like netdev, Greg, Andrew etc.

Every patch I apply to my subsystems is reviewed by me. I cannot do
else, because that is the requirement of maintainership.

There are however maintainers (see i2c patches or Intel DRM) who accept
patches and do not review them. When they review, they provide
additional Rb tag + Sob. This is weird because it means when they accept
patch, they take it unreviewed! Their SoB does not imply reviewing patch
and this is in contrast to kernel process.

BTW, Stephen Rothwell mentions this to every maintainer on adding their
tree to linux-next ("You will need to ensure that ... reviewed by you
(or another maintainer of your subsystem tree)").

IMO, this would mean such maintainers accept code which they do not
understand/review/care. They are just patch juggling monkeys who take
something and push it further without doing actual work.

That's not how maintainership should look like. Maintainer must take
reviewed code and, if other maintainers do not review, then they must
perform it.

It depends on people. As I said, I2C and DRM provide Review tag. For me
this is silly and suggest that all my work, that 1000 patches I took,
was not reviewed.

So you want to say, that you are fine in sending intentionally buggy
code, knowingly incorrect, because your SoB and your "git send-email"
does not mean you reviewed it?
