Just forgot to update after merging sound git tree.
Such a new build-stub has to be added manually. Fixed now.

tar.bz2 file is created on kernel.org server from tar.gz files
automatically. So when I upload a new tar.gz file, I delete tar.bz2
file beforehand. You seem to have looked at the directory just
between my upload and the rebuild of tar.bz2 by the server.
The same is true for alsa-driver-snapshot.tar.bz2, too, BTW.

alsa-driver-unstable-snapshot is created from a combination of
sound-unstable-2.6.git and alsa-driver-build-unstable.git trees,
while alsa-driver-snapshot is from a combination of sound-2.6.git and
alsa-driver-build.git trees. The commit ids of these trees are found
in alsa-driver*/HEAD and alsa-driver*/alsa-kernel/HEAD files.
The unstable tree is my playground. It's a place to keep experimental
patches and for integration tests. The alsa-driver-build-unstable
contains the needed build-stub for unstable tree. Thus these trees
may be rebased while sound.git and alsa-driver.git trees are basically
When sound git tree is updated, sound-unstable tree is also updated
automatically by git-merge. Sometimes the tree gets conflicts and
it's resolved manually, but usually a full automatic procedure.
alsa-kernel.git on alsa-project.org is another tree maintained by
Jaroslav, and it contains the kernel tree, i.e. corresponds to my
sound-2.6.git tree. I usually don't touch this at all because of too
alsa-driver.git on alsa-project.org is basically identical with the
one in kernel.org. It's sometimes out of sync because the
corresponding kernel git trees (sound.git and alsa-kernel.git)
differ. But when the kernel tree gets synchronized, alsa-driver.git
is also merged together.
alsa-kmirror.git tree is another different tree. It's a
self-contained alsa-driver tree including the kernel part. This is
also maintained by Jaroslav.
