I'm announcing the release of the 3.17.5 kernel.
No one should use it, use 3.17.6 instead. I'm just including this here
so that everyone can see the changelog of what went into it.
The updated 3.17.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-3.17.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
