To: linux-kernel, Andrew Morton, torvalds, stable
We (the -stable team) are announcing the release of the 2.6.22.3 kernel.
This release has a few bugfixes so all users of the 2.6.22 series are
encouraged to update to it. Especially people with laptops, they will
appreciate the power savings in this release.
I'll also be replying to this message with a copy of the patch between
2.6.22.2 and 2.6.22.3
The updated 2.6.22.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-2.6.22.y.git
and can be browsed at the normal kernel.org git web browser:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.22.y.git;a=summary
thanks,
greg k-h
