Subject: [PATCH] virtiofsd: remove mountpoint dummy argument
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8
|
|
Content-Transfer-Encoding: 8bit
|
|
|
|
Classic FUSE file system daemons take a mountpoint argument but
|
|
virtiofsd exposes a vhost-user UNIX domain socket instead. The
|
|
mountpoint argument is not used by virtiofsd but the user is still
|
|
required to pass a dummy argument on the command-line.
|
|
|
|
Remove the mountpoint argument to clean up the command-line.
