Well, OpenAFS hasn't changed behavior because I haven't heard a reason
for AUFS' behavior. I thought they could just lock the inode afterwards
and that would avoid this, while still pretty clearly not introducing
any other issues. That's what would sound most defensive/conservative to

for the behavior; we haven't been defending the existing behavior from
each other or anything.
As I mention in that linked message, the OpenAFS code maybe doesn't need
to be like that. I could give you a patch that would avoid this issue,
but I'm not sure if it causes any other problems; more time would need
to be spent looking at it to be sure. (Or you can just try it and see
