Hinting to userspace to do a retry (with -EAGAIN as you mention in your other mail) wouldn't be a bad thing at all, though you'd almost certainly get quite a few spurious -EAGAINs -- &{mount,rename}_lock are global for the entire machine, after all.I'd hope that we have some future (possibly very long-term) alternative that is not quite system-global, but yes, right now they are.
It ought to be reasonably easy to make them per-sb at least, I think. We don't allow cross-super rename, right? David
