Description
The VFS and file system drivers should support file system probing in order to avoid explicit file system type specification while mounting a block device. As it is common in other systems, the probing mechanism should kick in by using a reserved file system type "auto".

VFS/FS need to have an interface that allows getting information on the specified filesystem:
- does the device contain this type of filesystem? If so,
- filesystem instance ID
- volume name
This can be used by volsrv to probe for filesystem type (all filesystem servers must be loaded, though), and then based on the obtained information it can decide if/where to mount the file system.

VFS now supports VFS_IN_FSPROBE and the following file systems implement it:
- cdfs
- exfat
- ext4fs
- fat
- mfs
Besides locfs and tmpfs, only udf doesn't support this method.
