Subject: [RFC PATCH v8 07/19] af_vsock: update comments for stream sockets
Date: Tue, 13 Apr 2021 15:43:32 +0300 [thread overview]
Message-ID: <20210413124335.3401693-1-arseny.krasnov@kaspersky.com> (raw)
In-Reply-To: <20210413123954.3396314-1-arseny.krasnov@kaspersky.com>
This replaces 'stream' to 'connection oriented' in comments as
SEQPACKET is also connection oriented.
