I spent the drive to the Minneapolis Airport thinking about this chain
of e-mails.  Hope these thoughts help ...

I totally agree with this statement.  We have so many large patches to
review that it is daunting.  I wish I had a good solution for dealing
with this issue.  I don't think quick reviews and just trying to get
them through is the right answer.  Perhaps a coordinated effort for some
portion of our code sprint days to knock things down?  Split up the work
and then work together to push some through?

I can understand the frustration here, but do we want to discourage
people from doing this.  If they are submitting fixes, they are looking
at the code.  They are bound to also find some bugs in code as well.  I
just think it is dangerous to say that those changes have no real
improvement to the code.  That is just my feeling.  OpenStack, unlike
other projects I have been on, is very much like an open book.  Anyone
can read it and people often do.  I don't want Cinder to look like a
poorly written book.

Well, with regards to the misspellings, see my comment above.  I don't
think people are taking pride in hitting -1 over it.  They are seeing
issues, don't want to be submitting a bunch of clean-up patches and so
are noting that they think something needs to be fixed.

I agree the -1 needs to be used with care here.  Is it one typo or 20?
Are there a bunch of +1's and/or +2's on the review.  If so, shouldn't
be -1'ing at that point.  If people are throwing themselves in front of
the train, perhaps we need more education for the crew.

Duncan noted that perhaps his code clean-up weeks could help with this.
I hate to admit I don't fully understand how to use the process yet.  I
hope we can talk about that as well as this whole subject at the code

Also, I was surprised in one of your subsequent notes that you were
frustrated with the addition of Hacking checks.  I had been working on
those given that I thought it was part of the solution to all the -1's.
Catch some of the issues that are easily caught and also catch us up
with other project's Hacking checks.

Honestly, I haven't been able to get to the new feature stuff because I
am distracted by the little clean-up patches, but because the new
features are so big and painful I have been bad about forcing myself to
get through them.  I wonder how may are guilty of this?  :-)

Is this problem unique to Cinder?  I don't hear others talking about
this much.  If this is unique to Cinder, why?  Maybe we need to start
with that question to find a solution.
