h, and as some people already noticed, the numbering means that the
tar-balls and patches are now in a new directory:

    /pub/linux/kernel/v3.0

(under "testing/", since that's what we do with -rc releases).
However, I did *not* rename the git tree, because that would just be a
huge inconvenience to git users, so it's still in the same old place
and yes, that means that my git tree is still called "linux-2.6.git"
on kernel.org. But it has the v3.0-rc1 tag in it.

I'll probably add a symlink or something, if people really hate being
reminded about our long history with the "2.6" numbering. But that
won't be until closer to the real release, methinks.

First of all, congrats to Linux v3.0-rc1!

As you have found by yourself this new numbering forces a bit of
rethinking some of (y)our (daily) workflows.
( The new location of Linux v3.0-rc1 tarball was my 1st "problem" when
converting my kernel-buildsystem. )

[A] REPOSITORY NAMES

BUT...
...your GIT tree is still called "linux-2.6" :-).
Lots of other GIT repsoitories still use a prefix "linux-2.6-", like
linux-2.6-tip, linux-2.6-rcu, linux-2.6-acpi, or look at net-2.6 or
drm-2.6.
NOW...
...it would be a good point to rename all repos to a more general/common name.
Especially, the "linux-2.6-" can go to /dev/nirvana.
[1] lists all trees merged into linux-next and can be used as an overview.

Here some examples with proposals for change:

EXAMPLE #1: Repos containing "linux-2.6-" prefix (IMHO even "linux-"
as prefix can be dropped)

1. linux-2.6-tip -> tip
2. linux-2.6-rcu -> rcu
3. linux-2.6-acpi -> acpi

EXAMPLE #2: Repos containing "-2.6" as suffix

1. net-2.6 -> net
2. drm-2.6 -> drm
3. wireless-2.6 -> wireless
4. sound-2.6 -> sound

[ Gold medal to Ted for his ext4 GIT tree :-). ]

EXAMPLE #3: WTF trees not fitting #1 or #2

In general: Use the directory-name where your drivers are stored, see
also MAINTAINERS file.

EXAMPLE #4: Repos using a separate GIT repo with -next suffix (for linux-next)

1. net-next-2.6 -> net-next
2. wireless-next-2.6 -> wireless-next

I know people won't like the idea on 1st look and hate me for no real
benefit/new features, but...
...PLEASE...
...don't start renaming to "3.0", in a decade we have the same problem
:-( and thus do it right from the beginning.

Thoughts?

[B] MY EXPERIENCES WITH v3.0-rc1

Here my 1st impressions:
I am mostly on linux-next and working with an adopted
kernel-buildsystem from Debian kernel team.

As a quick workaround, I changed package-name from "linux-2.6" to "linux-3.0".
This also led to a new folder linux-3.0 below $HOME/src.

A two digits major version number like 3.0(-rc1) is (currently) not
accepted, so the first line of debian/changelog looks like this:

linux-3.0 (3.0.0~rc1-1~next20110530.dileks1) UNRELEASED; urgency=low

So, I used for now 3.0.0~rc1 (Note: Debian uses ~rcX in changelog files).

IIRC some READMEs, copyright files below debian-dir etc. have to be
adopted, too.
But as this work is for my personal amusement, I build 1st and enjoy...

$ cat /proc/version
Linux version 3.0.0-rc1-next20110530.1-686-small (Debian
3.0.0~rc1-1~next20110530.dileks1) (sedat.dilek@gmail.com) (gcc version
4.6.1 20110526 (prerelease) (Debian 4.6.0-10) ) #1 SMP Mon May 30
08:15:10 CEST 2011
