That's not bad as a start and it doesn't necessarily mean that there is 
anything wrong with ocfs2. There are many cases when SuS says that the 
behavior can be implementation specific.

But we did find that following ext3 as close as possible will reduce the 
number of bug reports. We started from "574/1950 subtests failed, 70.56% 
okay."
