Subject: qemuBuildIoEventFdStr: Always assume support for QEMU_CAPS_VIRTIO_IOEVENTFD
X-Git-Tag: v7.9.0-rc1~158
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=756ce0e50cf01e3939393c7596140fc4dc6823bf;p=thirdparty%2Flibvirt.git

qemuBuildIoEventFdStr: Always assume support for QEMU_CAPS_VIRTIO_IOEVENTFD

The support for the 'ioeventfd' knob of virtio devices was introduced by
QEMU commit 25db9ebe15125 contained in v0.14.0-rc0 and it can't be
compiled out. Thus libvirt can assume it's support and remove
conditional code.
