[Ocfs2-devel] [patch v2] ocfs2: fix recent memory corruption bug

[Dan Carpenter]

The pointer math in 6fdf3af1d2 "ocfs2: fix null pointer dereference in
ocfs2_dir_foreach_blk_id()" isn't correct so it will zero out the wrong
memory.  In fact, the memset isn't needed because the initializer will
set all these values to zero.
