Test cases are: 1) basic link creation, verify it can be followed 2) chained links, verify it can be followed 3) replace exiting file a with a link, and a link with a link. verify it can be followed 4) create a broken link, verify it can't be followed Signed-off-by: Jean-Jacques Hiblot <jjhiblot@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>
