Subject: [PATCH v12 01/77] KVM: UAPI: add error codes used by the VM introspection code
Date: Wed, 6 Oct 2021 20:29:57 +0300 [thread overview]
Message-ID: <20211006173113.26445-2-alazar@bitdefender.com> (raw)
In-Reply-To: <20211006173113.26445-1-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.
