I'm announcing the release of the 3.18.108 kernel.
All users of the 3.18 kernel series must upgrade.
The updated 3.18.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-3.18.y
and can be browsed at the normal kernel.org git web browser:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary
thanks,
greg k-h
