At some point there'd been a dumb braino during the dup_fd() calling conventions change; caught by smatch and immediately fixed. The trouble is, there had been no test coverage for the dup_fd() failure handling - neither in kselftests nor in LTP. Fortunately, it can be triggered on stock kernel - ENOMEM would require fault injection, but EMFILE can be had with sysctl alone (fs.nr_open).

Applied to linux-kselftest next for Linux 6.12-rc1 after fixing up the short log to reflect the right test.

Thank you.
