From ecc421e05bab97cf3ff4fe456ade47ef84dba8c2 Mon Sep 17 00:00:00 2001 From: Cyril Hrubis Date: Tue, 3 Mar 2020 16:06:38 +0100 Subject: sys/sysinfo: Respect boottime inside time namespace The sysinfo() syscall includes uptime in seconds but has no correction for time namespaces which makes it inconsistent with the /proc/uptime inside of a time namespace. Add the missing time namespace adjustment call.
