4Subject: [PATCH] cmd/gpt: Address error cases during gpt rename more correctly
5
6New analysis by the tool has shown that we have some cases where we
7weren't handling the error exit condition correctly. When we ran into
8the ENOMEM case we wouldn't exit the function and thus incorrect things
9could happen. Rework the unwinding such that we don't need a helper
10function now and free what we may have allocated.
