[LTP] [PATCH v4] mount_setattr02.c: Check mount_setattr attr propagation

[Cyril Hrubis]

Hi!
Pushed with some changes, thanks.


- We have to move the SAFE_UMOUNT(tmpdir) to the run() otherwise the test
  fails to cleanup() with -i 2

- Make sure that the slavedir was mounted shared before making it slave

- Minor adjustenment to the test description
