I'm announcing the release of the 5.13.1 kernel.

All users of the 5.13 kernel series must upgrade.

The updated 5.13.y git tree can be found at:
        git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-5.13.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;a=summary


Thanks,
Sasha
