From 8e0cd68ff4710c04229c8945feb145d1471e40fe Mon Sep 17 00:00:00 2001
From: Warner Losh <imp@FreeBSD.org>
Date: Fri, 1 Dec 2017 22:48:20 +0000
Subject: [PATCH] Correct history for Unix 2nd Edition through 6th Edition for
 the system calls. Man pages are missing for v2 and v5, so any entries for
 those versions were inferred by new implementations of these functions in
 libc.
