Is this step mistitled? There is no "common.h" in this round.
Ahhhh my pre-vacation brain managed to correctly edit the commit
message, but not the header
For that matter, when the series makes a big change like this round,
please update the cover letter so that those who are reading it
without having seen the prior rounds can understand what the series
is about. It will equally help those who have seen prior rounds,
too. what is going on. E.g. The cover letter of v1 emphasized why
moving many things to common.h was a great thing (and promised to
talk about it more in patch 3), but that focus certainly has shifted
in this iteration that no longer even creates "common.h", right?
That's correct. I'll reroll this series with an updated cover letter
and fixed commit header.
