No, it's *not* better than nothing.
The thing is, these reports MUST NOT go to "everybody". If they do, that
is actually *worse* than nothing, because people will just ignore them
entirely, since they aren't "directed".
The emails need to be directed to the appropriate parties, not go to
everybody. There is nobody who is interested in seeing all regressions,
except perhaps me and Andrew. Most *real* developers (as opposed to people
like me, who are integrators, not "real developers") want to be notified
about problems in *their* area, and if it's just automation that sends out
everything, it just dilutes the value of the thing, to the point where
people will ignore it even for the cases when they happen to be related to
what they do.

I don't know a lot of developers who actually read LKML. I know a lot of
people who look for interesting subject lines and interesting people, but
read LKML in the sense of reading everything? Not likely.
That's why I think Adrian did a great job: he took the "noise" and made it
somethng worth looking at! And part of that is very much to make it
directred to only relevant parties (yes, they *also* got cc'd to
linux-kernel, but people would get them in their personal mailboxes and
*not* feel like it was just noise that didn't matter to them!)

I personally refuse to have anything at all with bugzilla. The interface
is so horrible that it's just not worth my time. I know there are a few
people who use it productively, but I'm always amazed that they can do
that.
The *big* problem with bugzilla is that it's such a "detail-oriented"
thing. It's fine if you have *one* bug that you're tracking. But whenever
that's not the case, it's almost totally useless.
Let me put it another way: I would never use a source control system that
forces me to look at my 22,000 files one at a time. I think such a system
is fundamentally broken, because it makes it impossible to get the big
picture ("what changed in the last week" kind of thing). The same is true
of bugzilla: if you *know* which bug you're looking at, it's good. For
anythign else, it's almost worse than useless, exactly because there is no
way to get an overview.

.. and you claim that this shows that developers don't listen. I'd say it
shows the exact *opposite*: the users don't listen. There's a lot mroe
users than developers, and bugzilla is pretty much designed to let the
users "report and forget", which is exactly the *wrong* thing to do,
because it puts the onus on the developer.
(I've said this before, but I'll say it again: one thing that would
already make bugzilla better is to just always drop any bug reports that
are more than a week old and haven't been touched. It wouldn't need *much*
touching, but if a reporter cannot be bothered to say "still true with
current snapshot" once a week, then it shouldn't be seen as being somehow
up to those scare resources we call "developers" to have to go through
it).
So there are probably things that bugzilla could do to become more useful,
but I don't see that happening. We'd need either a smarter/better
bugzilla, or somebody who actually turns noise into real information.
Adrian did that (although in fairness to others, other people definitely
do it too. Dave Jones, for example. Very useful).

I do agree - one of the problems with the job is not that it's thankless
(I think we've had at least ten kernel developers, very much including me,
talking about how _useful_ it is), but there is definitely a lack of
glamour and probably interest.
I think it could be more interesting if part of the job was doing the
tools. Tools *are* important. Most of my actual _development_ for the last
couple of years has been on "git", not the kernel, but I think I was more
productive that way, so I don't think that's wasted time at all.
So yes, automation would be a good idea, but I don't think bugzilla is it.

Well, one thing to keep in mind is that the kernel really does have a
*lot* more development going on that most other projects.
I don't think you'll find another project that has about six megabytes of
diffs every release (every two months). That's really one of the
fundamental issues - things really *happen* in the kernel. A *lot* of
things. You can't take a breather - I can do "stabilization releases"
every once in a while, and Andrew can kick out patches he decides aren't
ready to be merged rather than maintain them in his tree (and he does do
that), but the kernel simply tends to have a different *scale* than other
projects.
And almost all hard bugs are about hardware interactions. Drivers. Big
iron. Things like that - ie unlike something like a compiler, you can
seldom say "this test-case crashes". Yes, that does happen for the kernel
too, but those are the *easy* bugs. Those generally get fixed in a day or
two.
So I really don't think you can compare to "other projects". They simply
don't have these issues.
