Linux 2.6.27.34

Linux 2.6.27.34

[Greg KH]

I'm announcing the release of the 2.6.27.34 kernel.  All users of the
2.6.27 kernel series are very strongly encouraged to upgrade.

I'll also be replying to this message with a copy of the patch between
2.6.27.33 and 2.6.27.34

The updated 2.6.27.y git tree can be found at:
        git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-2.6.27.y.git
and can be browsed at the normal kernel.org git web browser:
        http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.27.y.git;a=summary

thanks,

greg k-h
