This test case would try the following combinations:

- Valid cases
  * subvolume directly under fs tree
  * subvolume with several parent directories
  * subvolume path with unnecessary too many duplicated '/'s

- Invalid cases
  * subvolume path without any filename, e.g. "/////"
  * subvolume path with ".."
