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 usees fsstress to produce a small random load, to make sure basic operations on the bind mountpoints won't cause hang or panic etc. Signed-off-by: Zorro Lang <zlang@redhat.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu> Reviewed-by: Eryu Guan <eguan@redhat.com> Signed-off-by: Eryu Guan <eguan@redhat.com>
