Because the different files are in different subsystems. The cover letter
goes to a list for each file, or to a person if there is no list. The
patches go to the people and lists associated with the affected files.

there was discussion about this just some days ago. CC 4-5 lists is
more than enough

I don't know who you were discussing this with...
You should CC the 0th patch to all the mailinglists. That much is a
clear rule.
For the rest, Julia's position is the more conservative one. I was in
a conversation in RL and they were like, "CC everyone for all the
patches". It depends on the context, of course. If the patches are
dependent on each other then you *have* to CC everyone for everything.
If we really have other clear rules, then it should be encoded into
get_maintainer.pl so that it's automatic.
My other question is why do the linux-arm-kernel@lists.infradead.org
people feel like they need to be CC'd about every driver??? I always
remove them from the CC list unless it's an arch/arm issue.

dan carpenter

Agreed. Ms. Lawall, sending "Cover letter + all relevant XFS patches"
(as you did) was exactly the right thing for us xfs types. :)
For that matter, we prefer to receive through linux-xfs more patches
than necessary (one can send the entire series if one is unsure) than to
go wanting for more context.

Thanks for the confirmation. I was planning to ignore the 4-5 advice,
because there is no way in this case to make a meaningful 4-5 list
suggestion - it's either all or nothing. But 20 patches at once is
perhaps a lot as well. In this case, I just wanted to get rid of the
whole issue at once.

I assume I can take this to wireless-drivers-next. If you are planning
to push this via some other tree please let me know.
