[Ocfs2-tools-devel] [PATCH 50/50] fswreck: Add corruption for DUP_CLUSTERS_ADD_REFCOUNT.

[Tao Ma]

DUP_CLUSTERS_ADD_REFCOUNT is used to improve the process
we handle duplicated clusters. So we can just corrupt
the root extent block so that all the refcounted clusters
will be treated as duplicate clusters.
