Comments from Andreas

"I noticed that ".lustre" now appears in "ls -a" output, but I don't think that is supposed to happen. It might have been added when .lustre was created as a real inode in 2.4 or so?

This causes a problem because backup and other filesystem scanning tools will want to go into .lustre and read all the files there, and may also want to restore them after a crash, which could cause problems.

I think readdir needs to be fixed to not include the .lustre directory in readdir output. "
