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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
