On a 8 nodes cluster setup by xen, I tested these test cases,
- run_buildkernel.py
- cross_delete.py
- dlmstress1.sh
- run_extend_and_write.py
- run_lvb_torture.py
- mmap_test
- test_netfail.py

Not tested cases are run_create_racer.py and open_delete.py, cause I encountered some error when
setup them.

When I ran dlmsress1.sh and test_netfail.py,
- Kernel BUG at fs/ocfs2/dlm/dlmast.c:334 was triggered 3 times.
- Kernel BUG at fs/ocfs2/dlm/dlmmaster.c:1694 was triggered once.
Right now, there is not obvious clue they are directly related to this patch. They might stay there
already, I will do more testing to confirm.

Thanks.
