But I'm not aware of anything actually doing this. More importantly the admin can do it. And mandatory locking doesn't mean you can't remove something, with would be a complete nightmare. It also doesn't apply to directories, which from my reading of the patch this one would do. But yeah, doing the read/write part as as a special case of mandlock on open might make some sense, but I'm still not too convinced. That more I think about these option the less I like the idea, it's just going to cause a lot of problems to help with some wine issues that hasn't even been explained yet. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
