From: Zorro Lang <zlang@xxxxxxxxxx>
This case will do function test for mount bind operation, it will
verify below semantics:
---------------------------------------------------------------------------
| BIND MOUNT OPERATION |
|**************************************************************************
|source(A)->| shared | private | slave | unbindable |
| dest(B) | | | | |
| | | | | | |
| v | | | | |
|**************************************************************************
| shared | shared | shared | shared & slave | invalid |
| | | | | |
|non-shared| shared | private | slave | invalid |
***************************************************************************
This case use fsstress to produce a little rand load, to sure basic
operations on the bind mountpoint won't cause hang or panic etc.
