Do we track people dong this at all? I wonder how many patches in
linux-next have cc: stable in them but haven't been submitted to
Linus,

I know in some cases people want to soak test them for a bit longer
but not sure how much actual coverage next provides.

The other side of that coin is to wonder how many patches get marked
as "stable" when they definitely shouldn't be.

I know that's a non-empty set. Too many developers think that the
thing they fix is so important that it needs to be backported. And it
doesn't help that Greg is sometimes over-eager to take things without
them being even in my tree long enough to get much testing.

Quite frankly, if somebody has something in "next" (and really meant
for the _next_ merge window, not the current one) that is marked for
stable, I think that shows uncommonly bad taste. And that, in turn,
means that the "stable" tag is also very debatable. It clearly cannot
be important enough to really be for stable if it's not even being
aggressively pushed into the current -rc.

Well, I know of at least one regression fix that is waiting in linux-next
for the upcoming merge window and it most likely is tagged as -stable material.

The problem with the "stable" tag is that people have to add it before the patch
is put into their non-rebasing branches, which makes it appear in linux-next
before it goes to your tree.  This tag is arguably convenient for Greg, because
it allows him to automatically cherry-pick "stable" candidates from the
mainline, though.

There are 22 trees that get merged into in linux-next that are "bug fixes
for the current release" trees ... that was the list I sent you after the
-rc7 announcement (most of which I think you have since merged.  In
fact, there are currently only 5 commits in those 22 trees that you have
not merged.

The other thing people do is to add such bug fixes to their -next trees
before asking you to take them.

That's a tough thing to judge as I usually batch up stable
patches/releases every other week or so.  This can cause some patches to
be in your tree longer than others.

Should I just have a general "wait a week/release" type rule here before
adding them to a stable tree for most patches that aren't "obvious"?

I dunno. It's a judgement call, and not an easy one. We've had lots of
problems even with patches that are totally "obvious", simply because
there's some unintended interaction. So even when the patch looks
obviously correct on a small scale (especially just the 3-line
context), it may not be obviously correct after all. In fact, when
people find a bug, the bug it introduced may well be totally obvious
after-the-fact.

So I think it might be a good idea to have some automated "don't send
patches to 'stable' immediately when merged into the tree - wait a
week". At the same time, I don't really think it will work. Some
patches you're probably better off taking immediately (_despite_ the
risk - however low it is - that the thing has some subtle
interaction).

And I suspect that from a social standpoint, if we delay the stable
queue auto-patch-sending, it will just lead to people trying to bypass
that delay by sending things directly to stable rather than depending
on the "stable@kernel.org" tag on the commit itself. Or if the delay
is implemented on the stable email address itself, then people would
try to just send it directly to you instead.

It doesn't help that the number of patches in a stable release is much
bigger than at least I personally envisioned. Yes, many of them are
things like adding device ID's etc, but I do suspect that it just then
makes it much harder to try to delay things by a week or something.
Plus some problems probably wouldn't even be noticed in a week in the
development kernel, and they'd _still_ be found only once it hits
stable just because lots of people will obviously never test the
development kernel.

So I have no solution to it. I just don't think stable has been quite
as stable as people would wish for.

I agree, that would just get messier.

The "largeness" of recent stable kernel releases (i.e. for the past
year) seem more to be a factor of the subsystem maintainers finally
realizing that they should be sending their bugfixes to me (thanks a
large part to Andrew's constant badgering about this), combined with the
distros sending me their bugfixes that they have found that are already
included upstream.

It hasn't?  I haven't heard people saying anything about this before, in
fact, people seem to get upset at me when I reject the stuff they are
sending me for inclusion which don't meet the stable criteria.

Not that I'm trying to say, "it could be worse", just that, "what could
be done better?"

Quickly searching my email for "bisect" and "stable" gets a few hits
for 2.6.35. One was the problems with the stack guard page in
2.6.35.2, another was some CPU usage issue in 2.6.35.4.  And there was
the scheduler problem in 2.6.32.y or whatever (but that was a "done
differently from mainline" situation, so it was a different kind of
patch entirely).

And there probably are others that my silly search just didn't see.

I really don't know. I suspect that a certain amount of problems are
always going to be inevitable. It's not like you can avoid regressions
entirely, at least not unless you take the "it's dead, Jim" approach
to stable.

Yeah, I do feel I keep some of the stable trees around longer then I
should, I've been working to keep that from happening any more in the

Good idea.  The "stable" branch of linux-next is just where in Linus'
tree that's day's linux-next was based.

# Friday's linux-next:
$ git log --pretty=oneline -i --grep="cc:[ 	]*stable" stable.. | wc -l
71
# origin/master is Linus' current tree
$ git fetch origin
$ git log --pretty=oneline -i --grep="cc:[ 	]*stable" origin/master.. | wc -l
70
# so at least one went in over the weekend

Some of these will be false positives because commits get rebased before
being sent to Linus (quilt trees especially).

Here is the result of
"git log --pretty=short -i --grep="cc:[ 	]*stable" origin/master.."

Wow, that's a lot.

Yes, but still, your list looks correct.

New device ids are something trivial which I mark for stable, but
usually hold off on submitting this late in the release cycle as it just
takes up time for everyone involved and they aren't a big deal.

Others in my tree are stuff that are "nice to have" but not essencial
for .37 at all for this point in time.

Then there's the wireless tree, which always loves to tag stuff and then
provide backports, but they want the stuff tested in Linus's tree first,
which is fine, so it waits for the next release.

thanks for the list,
