I'm announcing the release of the 2.6.37.6 kernel.
All users of the 2.6.37 kernel series must upgrade.
No, scrap that, they should move to the 2.6.38 kernel series as the .37
series is now end-of-life and will get no more updates.
The updated 2.6.37.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-2.6.37.y.git
and can be browsed at the normal kernel.org git web browser:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.37.y.git;a=summary
thanks,
greg k-h
