Thanks, yeah email for development is a complete pain to be honest! I wouldn't say that the cc list in any way would be perceived as self-aggrandizing, I mean some of the trivial stuff I've sent to larger cc lists :P But I get your point, it's a kind of impossible balancing act :) > > So what you're looking at is a (poor) attempt at trimming down the CC > list based on who I had talked to about these patches at the THP > meeting and who I remember had worked on shrinkers & cgroups. > > I can CC everybody going forward, not a problem. Personally I don't > mind getting CCd generously, but my understanding is that some people > do... Yeah I have often sent series where the list felt... egregiously huge, but I _generally_ treat it as - people are used to getting tonnes of mail - so some more shouldn't hurt. I mean in [0] for example I really cringed at sending a 23 patch series that is super super mm-centric and really just updating how we manage VMA flags (trying to get away from system word size flags) - to a trillion people. TL;DR - anyway, I think get_maintainer.pl --nogit (and trim anyone who isn't listed as a maintainer or reviewer) is the right balance to take - maintainers with screwed up email set ups (*cough* naming no names beginning with L and ending with orenzo) and reviewers who have signed up for lots of mail I think are totally fine to always send to. And of course +cc anybody else you feel appropriate. The 'git' maintainers entries can absolutely be dropped though, unless you're explicitly say radically changing something somebody contributed and it makes sense to include them though all that's subjective!
