We (the -stable team) are announcing the release of the 2.6.21.2 kernel.
This release has a large number of bugfixes in many areas.
I'll also be replying to this message with a copy of the patch between
2.6.21.1 and 2.6.21.2
The updated 2.6.21.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-2.6.21.y.git
and can be browsed at the normal kernel.org git web browser:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.21.y.git;a=summary
thanks,
-chris
