[PATCH v3 0/7] Add series support

[Daniel Axtens]

Hi Stephen,

This series causes a > 2x jump in the number of SQL queries required to
display the front page. With my test of some emails from the patchwork
mailing list, it goes from 73 queries on master to 182 queries, and the
time spent in SQL also more than doubles.

That's highly problematic.

We need to debug and fix this before merging. I'm currently
investigating, but if you have any insights that would be great.

Regards,
Daniel
