From f411fbba85151c4795c35d2764d1731a0ea94683 Mon Sep 17 00:00:00 2001 From: cheloha Date: Fri, 26 Jun 2020 18:48:32 +0000 Subject: timecounting: deprecate time_second(9), time_uptime(9) time_second(9) has been replaced in the kernel by gettime(9). time_uptime(9) has been replaced in the kernel by getuptime(9). New code should use the replacement interfaces. They do not suffer from the split-read problem inherent to the time_* variables on 32-bit platforms. The variables remain in sys/kern/kern_tc.c for use via kvm(3) when examining kernel core dumps. This commit completes the deprecation process: - Remove the extern'd definitions for time_second and time_uptime from sys/time.h. - Replace manpage cross-references to time_second(9)/time_uptime(9) with references to microtime(9) or a related interface. - Move the time_second.9 manpage to the attic.
