I'm announcing the release of the 4.9.306 kernel.
All users of the 4.9 kernel series must upgrade.
The updated 4.9.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-4.9.y and can be browsed at the normal kernel.org git web browser: https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git%3Ba=summa...
thanks,
greg k-h
