Yeah, I think this is the right thing to do. Patch upthread [0].
For back-branches, I suspect we'll want to remove all uses of
durable_rename_excl() but leave the function around for any extensions that
are using it. Of course, we'd also need a big comment imploring folks not
to add any more callers. Another option would be to change the behavior of
durable_rename_excl() to something that we think is safer (e.g., stat then
rename), but that might just introduce a different set of problems.
