From 817dbdfdf8ee10c524a15f7247a3742cb926f96b Mon Sep 17 00:00:00 2001 From: Matthew Heon Date: Tue, 9 Jun 2020 14:05:45 -0400 Subject: Ensure signal validation happens first in pod kill This fixes an error in the system tests, which expect that when you try and kill a nonexistent pod with an incorrect signal, you receive an error about the signal, not the pod. At the same time, fix a missing return statement in the bindings, which could also have caused us grief.
