Subject: [RFC PATCH v1 1/2] vsock: return errors other than -ENOMEM to socket
Content-Type: text/plain; charset="UTF-8"
Content-Transfer-Encoding: 7bit
Precedence: bulk

This removes behaviour, where error code returned from any transport
was always switched to ENOMEM. This works in the same way as:
commit
c43170b7e157 ("vsock: return errors other than -ENOMEM to socket"),
but for receive calls.
