I'm announcing the release of the 2.6.32.39 kernel.
All users of the 2.6.32 series must upgrade.
The updated 2.6.32.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/longterm/linux-2.6.32.y.git
and can be browsed at the normal kernel.org git web browser:
http://git.kernel.org/?p=linux/kernel/git/longterm/linux-2.6.32.y.git;a=summary
thanks,
greg k-h
