From d34c30cc1fa80f509500ff192ea6bc7d30671061 Mon Sep 17 00:00:00 2001 From: Juergen Gross Date: Tue, 26 Jul 2016 14:15:11 +0200 Subject: [PATCH] xen: add static initialization of steal_clock op to xen_time_ops pv_time_ops might be overwritten with xen_time_ops after the steal_clock operation has been initialized already. To prevent calling a now uninitialized function pointer add the steal_clock static initialization to xen_time_ops.
