Linux 2.6.27.56

Linux 2.6.27.56

[Greg KH]

I'm announcing the release of the 2.6.27.56 kernel.

All users of the 2.6.27 kernel series must upgrade.

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
