From 89b516d8b9444ece8ccabb322a9389587c7a7b83 Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Wed, 15 Oct 2014 14:29:30 +0200 Subject: glib: add compatibility interface for g_get_monotonic_time() This patch fixes compilation errors when building against glib <2.28.0 due to the missing g_get_monotonic_time() function. The compilation error in tests/libqos/virtio.c was introduced in commit 70556264a89a268efba1d7e8e341adcdd7881eb4 ("libqos: use microseconds instead of iterations for virtio timeout"). Add a simple g_get_monotonic_time() implementation to glib-compat.h based on code from vhost-user-test.c.
