Subject: [RFC PATCH v1 3/7] vhost/vsock: support MSG_EOR bit processing
Date: Mon, 26 Jul 2021 19:33:38 +0300 [thread overview]
Message-ID: <20210726163341.2589759-1-arseny.krasnov@kaspersky.com> (raw)
In-Reply-To: <20210726163137.2589102-1-arseny.krasnov@kaspersky.com>
It works in the same way as 'end-of-message' bit: if packet has
'EOM' bit, also check for 'EOR' bit.
