Glad to see that it isn't totally broken. I am by no means an expert in
the ZFS code, and I am not in a position to take a lot of time looking
at it right now, but if the trace back in the PR is correct, it makes it
almost totally though the mkdir call and crashes in the log create step
after the directory node is created. I am trying not to speculate too
much here, but the code may fail to handle the group in the exports
