Hi all,

I have created the first cut of the linux-next tree at
git://git.kernel.org/pub/scm/linux/kernel/git/sfr/linux-next.git.

Things to know about this tree:

It has two branches - master and stable.  Stable is currently just Linus'
tree and will never rebase.  Master will rebase on an almost daily basis
(maybe slower at the start).

The tree consists of subsystem git and quilt trees.  Currently, the quilt
trees are integrated by importing them into appropriately based git
branches and then merging those branches.  This has the advantage that
any conflict resolution will onlt have to happen once at the merge point
rather than, possibly, sevveral times during the series.  However, I am
considering just applying the quilt trees on top of the current tree
to get a result more like Linus' tree - we will see. The git trees are
obviously just merged.

Between each merge, the tree was built with both an allmodconfig for both
powerpc and x86_64.

The tree currently contains:
	Greg's driver-core, pci and usb quilt series (in that order)
	Alasdair Kergon's device-mapper quilt tree
	Jiri Kosina's hid git tree
	Jean Delvare's i2c quilt tree
	Randy Dunlap's kernel-doc quilt tree
	Haavard Skinnemoen's avr32 git tree

There was only one unresolved conflict which could have been caused
because I was not sure where to base the kernel-doc tree.

So, comments, please.

Also, more trees please ... :-)

Now, would it be possible to have somewhere listed the URLs of git/quilt 
trees that were merged? The commit messages about merges with different 
branches aren't too informative, it might sometime be useful to know more 
about the trees that were merged.

Maybe just an additional file somewhere in the root of the source tree 
would be sufficient ...

Thanks,

Rafael has it right, please add the branch above.
It will include both the upcoming ACPI and suspend patches.

Note that I reserve the right to re-base it from time to time -
so when you pull it, you want to pull it onto a new branch vs. Linux
rather than onto a previous copy of itself.

From: Andy Whitcroft
Date: Thursday, February 14, 2008 - 9:04 am

As devout believers in testing things early we test -mm and -git releases
as they drop.  I am keen that we are able to continue this with the -next
tree once it gets going.  Having just pulled this tree its not obvious how
I would communicate which tree I had tested.  I guess we could use the
SHA1 of the actual head used, but that really is cumbersome for the poor
people who have to check the results and actually report things to lkml.

As I previously indicated (on my stupidly subjected "testing linux-next")
to make it simple for us to test these releases, and for the reporters to
have a clear way to refer to them, we need some kind of sensible handle
for each.  It is also very desirable that it be trivial for a script to
detect releases.  The -git series is pretty handily named, following that
example might make sense.

I was going to propose you name them in a similar way to the main -gitN
releases.  But, I note that you are merging with what appears to be an up to
date Linus master tree.  Which means there is no nice name for the real
base point for your merges anyhow.

I guess there are a couple of sensible names for these.  Either a simple
date or using the nearest sane tag.

So either:
	next-20080214
or:
	v2.6.25-rc1-next1

Where the "base" version would be determinable from:
	apw@pinky$ git describe --tags origin/stable
	v2.6.25-rc1-120-ge760e71

I am guessing if a maintainer is coming back to look at a failure
reported by yourself, they are also going to want to know what the base
was for the merge which failed.  So it may make sense to keep a tag for
that too?

Also will you be producing any tarballs for these releases?  If so I
would say they would definatly need to be against some common base, like
against the nearest official tag "below".

Please add v4l-dvb tree, at:

ssh://master.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-next.git

The above tree has two branches: 'master' and 'stable'

Both branches will have V4L/DVB next patches. The first is against your master,
and the second, against your stable.

I've opted to have both trees, since probably 'stable' is the better option for
you to clone. On the other hand, 'master' allow me to foresee if an "alien"
patch would conflict with a subsystem patch.

Could you change the Makefile to show that if we build and run this

different, but that might not be very obvious to people reading bug

Just adding "-next" to the extraversion would be great.

Please add the 'NEXT' branch of
git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev.git

to your list.  This is a throwaway meta-branch that is rebased often.

The 'master' branch of libata-dev.git always contains the base commit 
from torvalds/linux-2.6.git from which all other branches are based.  I 
never ever commit to the 'master' branch, only update it from 
torvalds/linux-2.6.git.


Andrew,

I will continue to maintain the 'ALL' branch exactly as before.  It may 
contain changes not suitable for 'NEXT', but suitable for -mm testing.

In my new development process, things will almost always land in 'ALL' 
before 'NEXT'.

From: James Bottomley
Date: Thursday, February 14, 2008 - 2:26 pm

So does this indicate the meaning of upstream and upstream-fixes is
still the same?  I always took upstream-fixes to be bug fixes for this
-rc and upstream as queued for the next merge window, in which case NEXT
would be the union of those two sets?

James


--

From: Jeff Garzik
Date: Thursday, February 14, 2008 - 2:45 pm

In practice, #upstream-fixes isn't very useful, because I send its 
contents to Linus very very rapidly once they are committed to that 
branch.  I then locally delete that branch once Linus merges it, and 
re-create it [again, locally] the next time I have some bug fixes to apply.

So it is a "somewhat throwaway" branch.

The main utility of #upstream-fixes is so that I can do
	git branch upstream-linus upstream-fixes
and then continue making commits in parallel with a Linus pull+push cycle.

The #upstream branch is much more useful, because that is where things 
for the next kernel are stored, during a bug-fix-only cycle.  This is 
largely equivalent to NEXT, though I plan to be more stringent in my 
requirements for NEXT commits than #upstream commits.

One thing to note is that "pure" rebases are somewhat rare; I much 
prefer to wait until the batch of commits lands in 
torvalds/linux-2.6.git, before I blow away and recreate (with a new 
torvalds HEAD) the branch in question.


So, to answer your question...  Fixes should go upstream fast enough 
that they should hit NEXT implicitly via a Linus pull+push.  It should 
be the union of two sets, yes, if a Linus cycle takes a long time.  When 
both #upstream and #upstream-fixes are active, I tend to always branch 
#upstream off of #upstream-fixes and/or do a "git pull . upstream-fixes" 
when updating #upstream.

Hi Stephen,
I would like to update the "The development process" section in
Documentation/HOWTO including some information about the linux-next tree.

I understand what it's including but I didn't get how it will fit in
the process.
Is Linus going to pull from that tree as soon as we reach -rc0 or this
is just a tree
used for testing what will be pushed to Linus as soon as the two weeks
merge window
open?

Thanks.

Ciao,

Hi Paolo,

The intention is the latter.  I hope to help people sort out some of the
conflicts and cross subsystem issues before we get into the merge window
and the code gets into Linus' tree.

Andrew Morton also hopes that the linux-next tree may get more testing
that the -mm tree did if we can stop it having to many regressions by
only including the less experimental code that is destined for the next
kernel release.
