I'm announcing the release of the 2.6.33.4 kernel.
All users of the 2.6.33 kernel series should upgrade.
Many thanks to maximilian attems for all of his work in submitting
patches for this release, it is much appreciated.
The updated 2.6.33.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-2.6.33.y.git
and can be browsed at the normal kernel.org git web browser:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.33.y.git;a=summary
thanks,
greg k-h
