To: linux-kernel, stable, kernel-team
I am announcing the release of the 3.5.7.9 tree of stable patches.
This tree picks up the latest 3.5 stable release upstream, and add patches
on top that were later marked for stable but can't be added to 3.5, as
it is not anymore an stable series maintained upstream.
The tree is maintained by the Ubuntu Kernel Team, with the intention
to continue to provide support for the 3.5 series. Anyone is welcomed
on using it or contributing to this effort.
For more info, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable
The updated 3.5.y tree can be found at:
git://kernel.ubuntu.com/ubuntu/linux.git linux-3.5.y
The diffstat and shortlog with changes since previous v3.5.7.8 release are
shown below.
-Luis
