We have been calling it virtio_fs and even file name is virtio_fs.c. Module
name is virtio_fs.ko but when registering file system user is supposed to
specify filesystem type as "virtiofs".
Masayoshi Mizuma reported that he specified filesytem type as "virtio_fs" and
got this warning on console.
------------[ cut here ]------------
request_module fs-virtio_fs succeeded, but still no fs?
WARNING: CPU: 1 PID: 1234 at fs/filesystems.c:274 get_fs_type+0x12c/0x138
Modules linked in: ... virtio_fs fuse virtio_net net_failover ...
CPU: 1 PID: 1234 Comm: mount Not tainted 5.4.0-rc1 #1
So looks like kernel could find the module virtio_fs.ko but could not find
filesystem type after that.
It probably is better to rename module name to virtiofs.ko so that above
warning goes away in case user ends up specifying wrong fs name.
