| * In the user.* namespace, only regular files and directories can |

| * |
| * There are 7 test cases: |
| * 1. Set attribute to a regular file, setxattr(2) should succeed |
| * 2. Set attribute to a directory, setxattr(2) should succeed |
| * 3. Set attribute to a symlink which points to the regular file, |
| * setxattr(2) should return -1 and set errno to EEXIST |
| * 4. Set attribute to a FIFO, setxattr(2) should return -1 and set |
| * errno to EPERM |
| * 5. Set attribute to a char special file, setxattr(2) should |
| * return -1 and set errno to EPERM |
| * 6. Set attribute to a block special file, setxattr(2) should |
| * return -1 and set errno to EPERM |
| * 7. Set attribute to a UNIX domain socket, setxattr(2) should |
| * return -1 and set errno to EPERM |
