The delays always happen when you do these patch bombs. In fact, that's
how I knew you sent them just now. My patches finally arrived, just under 8
hours since I sent them!

I'm not sure what I can do to help out. I'm not a very good email admin.
(I'm struggling to fix my wife's email now).

You already Cc stable@xxxxxxxxxxxxxxx. Does lore track that?

My point is, LKML has what, 10,000 subscribers? Maybe only 5000? Even at
5000, probably at most 50 subscribers look at the stable patches (and I'm
being optimistic). That means, these 3000 emails go to 4950 people that
will never look at them. That's 14,850,000 emails that are wasting disk
space, CPU cycles and electricity. Think of the environment :-)

I'm not saying that they should not be sent out. I'm asking, do they need
to be sent out to the list with the most subscribers? You already
(rightfully) Cc the maintainers of the patches. Since they already go to
the stable list, and if lore archives them, then you could just send a link
to LKML to the lore patch set. Then people could still review them.

Do those that review these patches really just read LKML to do so?

Or is this the spam approach of sending out to 1000x more than you need to,
just so that you get a few more eyes?

And the issue I have with this, is that it affects *all* mailing list on
vger not just LKML. I don't read LKML anymore, but I do read the smaller
lists. And blocking emails for 8 hours to these lists does have an effect on
productivity.
