Linux 3.2.44
From: Ben Hutchings
Date: Fri Apr 26 2013 - 07:43:00 EST
I'm announcing the release of the 3.2.44 kernel.
All users of the 3.2 kernel series should upgrade.
The updated 3.2.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-3.2.y
and can be browsed at the normal kernel.org git web browser:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git
The diff from 3.2.43 is attached to this message.
Ben.
