Subject: [PATCH v10 01/81] KVM: UAPI: add error codes used by the VM introspection code
Date: Wed, 25 Nov 2020 11:34:40 +0200 [thread overview]
Message-ID: <20201125093600.2766-2-alazar@bitdefender.com> (raw)
In-Reply-To: <20201125093600.2766-1-alazar@bitdefender.com>
These new error codes help the introspection tool to identify the cause
of the introspection command failure and to recover from some error
cases or to give more information to the user.
