To: linux-kernel, Andrew Morton, torvalds, stable; +Cc: lwn
I'm announcing the release of the 2.6.35.8 kernel.
All users of the 2.6.35 kernel series must upgrade.
There will only be one more .35 kernel released after this one, so you
should be using .36 instead.
The updated 2.6.35.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-2.6.35.y.git
and can be browsed at the normal kernel.org git web browser:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.35.y.git;a=summary
thanks,
greg k-h
