    That 'meaningful' was supposed to be a 'meaningless' of course.

    The point really is that we have about 1 new version number per week, but
    at the same time we have an average of one _thousand_ commits merged per
    week. So at a glance, the Makefile version number doesn't mean very much.

    But if the thousand commits we merged actually were nicely spread out in
    between those version numbers, it would all work really beautifully. Sure,
    the top-level version number would only give you a 1/1000 of the real
    commit information, but hey, that's kind of what you'd want, isn't it? So
    then the top-level Makefile version number would be meaningful and useful!

    But that's not how it works. In fact, if we actually followed our own
    release rules ("merge window is for merging code that was written before
    the merge window even started"), no commits except for my merge commits
    should actually have that last release in their Makefile at all!

    Now, that's not actually true, because (a) people rebase and (b) even in
    the absense of rebases I do merge with people like Andrew by email, so we
    actually end up having statistics like these:

    git rev-list v2.6.31..v2.6.32-rc1 |
    while read a
    git show $a:Makefile | grep SUBLEVEL.=
    done | sort | uniq -c

    resulting in

    32 SUBLEVEL = 29
    383 SUBLEVEL = 30
    8795 SUBLEVEL = 31
    1 SUBLEVEL = 32

    which is actually a bit sad in itself (showing just _how_ many people
    rebased their work on top of a release), but is still showing that we
    actually had 32 new commits in there that were based on a 2.6.29 kernel

    And what people are suggesting with a 2.6.32-rc0 would just lead to people
    now rebasing their work NOT EVEN ON A RELEASE. They'd want to rebase it on
    top of that made-up commit (2.6.32-rc0), so now from a development
    standpoint that commit suddenly becomes more important than the release

    Do you not see the insanity? We should have _less_ of this kind of
    thinking, not more. At least rebasing on top of a release sounds sane. Not
    this kind of "rebase on top of a magic Linus-commit" crap.
