Linux 6.12.1

Linux 6.12.1

[Greg Kroah-Hartman]

I'm announcing the release of the 6.12.1 kernel.

All users of the 6.12 kernel series must upgrade.

The updated 6.12.y git tree can be found at:
	git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-6.12.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,

greg k-h
