From 745f2bf4a5b973d1a69b21db97f9e4219da60624 Mon Sep 17 00:00:00 2001 From: Max Reitz Date: Wed, 9 May 2018 21:43:01 +0200 Subject: [PATCH] iotests.py: Add qemu_io_silent With qemu-io now returning a useful exit code, some tests may find it sufficient to just query that instead of logging (and filtering) the whole output.
