virtiofsd: add some options to the help message (2020-01-23 10:54:49 +0000)
----------------------------------------------------------------
virtiofsd first pull
Import our virtiofsd.
This pulls in the daemon to drive a file system connected to the
existing qemu virtiofsd device.
It's derived from upstream libfuse with lots of changes (and a lot
trimmed out).
The daemon lives in the newly created qemu/tools/virtiofsd
Signed-off-by: Dr. David Alan Gilbert <dgilb...@redhat.com>
