Determining a file system type

The type of a file system can be determined with 
$ df -T
Alternatively, the type can be determined with 
lsblk -f

Registering a file system

A file system is registered by calling register_filesystem() and unregistered by calling unregister_filesystem().
Both functions take a struct file_system_type* parameter (Defined in /include/linux/fs.h).

Special and pseudo file systems

Some file systems are not related to a disk:
tmpfs An in-memory file system (so data is not persisted)
procfs and sysfs They provide to kernel information about processes, devices and drivers
