From 45bd0b41bdbf554e49fb510673309164c513a8c8 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Thu, 7 Jan 2016 16:55:23 +0300 Subject: trace: split trace_init_events out of trace_init_backends This is cleaner and has two advantages. First, it improves error reporting with -daemonize. Second, multiple "-trace events" options now cumulate. Signed-off-by: Paolo Bonzini Signed-off-by: Denis V.
