Subject: Linux 3.16.53
I'm announcing the release of the 3.16.53 kernel.
All users of the 3.16 kernel series should upgrade.
The updated 3.16.y git tree can be found at:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-3.16.y
and can be browsed at the normal kernel.org git web browser:
https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git
The diff from 3.16.52 is attached to this message.
Ben.
