== sanity-lfsck test 23c: LFSCK can repair dangling name entry (3) == 02:09:55 (1446948595)
#####
The objectA has multiple hard links, one of them corresponding
to the name entry_B. But there is something wrong for the name
entry_B and cause entry_B to references non-exist object_C.
In the first-stage scanning, the LFSCK will think the entry_B
as dangling, and re-create the lost object_C. And then others
modified the re-created object_C. When the LFSCK comes to the
second-stage scanning, it will find that the former re-creating
object_C maybe wrong and try to replace the object_C with the
real object_A. But because object_C has been modified, so the
LFSCK cannot replace it.

Inject failure stub on MDT0 to simulate dangling name entry
