Linux 3.19.7

From: Greg KH
Date: Thu May 07 2015 - 19:11:06 EST

I'm announcing the release of the 3.19.7 kernel.

All users of the 3.19 kernel series must upgrade.

The updated 3.19.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-3.19.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
