[$] Reducing patch postings to linux-kernel

The linux-kernel mailing list famously gets an enormous amount of email on adaily basis; the volume is so high that various email providers try torate-limit it, which can lead to huge backlogs on the sending side and, of course, delayed mail. Part of the reason there is so muchtraffic is that nearly every patch gets copied to the mailing list, evenwhen it may be unnecessary to do so. A proposed changewould start shunting some of that patch email aside and, as might beguessed, has both supporters and detractors, but the discussion doeshighlight some of thedifferent ways the mailing list is used by kernel developers.
