Can you suggest me where I can get some good documents to proceed or any
dummy code if any.

See fs/ramfs/ for an example. There's also Documentation/filesystems/vfs.txt.

I have tried this with the following code but it gives some warning
messages during compilation. The file system is registered but during
the mount command segmentation fault occurs.

So maybe pay attention to the warnings?

static struct super_block *rfs_read_super( struct super_block *sb, void
*buf, int size);
static struct file_system_type rfs = {"rfs", 0, rfs_read_super, NULL};

There's no read_super in struct file_system_type. See
include/linux/fs.h for details.

int init_module(void) {

void cleanup_module(void) {

This is the old way. You really want to be using module_init and
module_exit macros.
