I came up with some very pretty code to fix this, which tried to copy_to_user with a lock held.
After all my attempts to fix that fatal flaw resulted in much uglier code I set it aside for a while in the hopes that inspiration would strike.
and it's still sitting unfinished. :-(
But I want to finish it, honest! This latest discussion has made me acutely conscious of it.
The fact that the scope of changes just got bigger doesn't help of course, but I *have* picked it up again.
