It's quite likely, if that system is checking the procfs-creation return value. So I think it'd be best if we were to detect the duplication and print a warning (which should include, if possible, the full pathname and a dump_stack()) and then the code should proceed as normal: permit the duplicated entry and return success. Then, when such duplicates are reported, we can work out what to do about them on a case-by-case basis.
