To: linux-kernel, Andrew Morton, torvalds, stable; +Cc: lwn
I'm announcing the release of the 2.6.35.9 kernel.
All users of the 2.6.35 kernel series must upgrade.
Please note, the 2.6.35 kernel is now "End Of Life" and will not be
getting any more updates. Please move on to using the .36 kernel series
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
