I'm announcing the release of the 4.4.102 kernel.

It's a bugfix for an issue if PAGE_POISONING is enabled in the kernel
configuration.  If you do not run your kernel with that option, no need
to upgrade, just stick with 4.4.101.

The updated 4.4.y git tree can be found at:
	git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-4.4.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;a=summary

thanks,

greg k-h
