To: linux-kernel, Andrew Morton, torvalds, stable
I'm announcing the release of the 2.6.27.23 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
2.6.27.22 and 2.6.27.23
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
