I am announcing the release of the Linux 3.16.7-ckt21 kernel.
The updated 3.16.y-ckt tree can be found at:
git://kernel.ubuntu.com/ubuntu/linux.git linux-3.16.y
and can be browsed at:
http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.16.y
The diff from v3.16.7-ckt20 is posted as a follow-up to this email.
The 3.16.y-ckt extended stable tree is maintained by the Canonical Kernel Team.
For more info, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable
