fs: FS_IOC_GETUUID
Add a new generic ioctls for querying the filesystem UUID.
'struct fsuuid' has a length field, so that these can be used for old
weird filesystems without a real UUID (vfat). The length must never
be more than 16 bytes.
This patch adds a generic implementation of FS_IOC_GETFSUUID, which
reads from super_block->s_uuid.
