commit 4cd273bb91b3001f623f516ec726c49754571b1a upstream.
(not in Linus's tree now, but in nf.git + linux-next.git already.)
age is signed integer, so result can be negative when the timestamps
have a large delta. In this case we want to discard the entry.
Instead of using age >= 2 || age < 0, just make it unsigned.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
