[Qemu-devel] [PATCH 1/4] virtiofsd: make -f (foreground) the default

[Stefan Hajnoczi <stefanha@redhat.com>]

According to vhost-user.rst "Backend program conventions", backend
programs should run in the foregound by default.  Follow the
conventions so libvirt and other management tools can control virtiofsd
in a standard way.
