| /* |
| * DESCRIPTION |
| * 1. Use a component of the pathname, which is not a directory |
| * in the "path" parameter to statfs(). Expect ENOTDIR |
| * 2. Pass a filename which doesn't exist, and expect ENOENT. |
| * 3. Pass a pathname which is more than MAXNAMLEN, and expect |
| * ENAMETOOLONG. |
| * 4. Pass a pointer to the pathname outside the address space of |
| * the process, and expect EFAULT. |
| * 5. Pass a pointer to the buf paramter outside the address space |
| * of the process, and expect EFAULT. |
| * 6. Pass a filename which has too many symbolic links, and expect |
| * ELOOP. |
