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


From: Stefan Hajnoczi
Subject: [Qemu-devel] [PATCH 1/4] virtiofsd: make -f (foreground) the default
Date: Tue, 27 Aug 2019 10:54:34 +0100

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.
