Subject: [RFC PATCH v2 07/13] af_vsock: update comments for stream sockets.
Date: Fri, 15 Jan 2021 08:42:59 +0300	[thread overview]
Message-ID: <20210115054302.1456496-1-arseny.krasnov@kaspersky.com> (raw)
In-Reply-To: <20210115053553.1454517-1-arseny.krasnov@kaspersky.com>

This replaces 'stream' to 'connect oriented' in comments as SEQPACKET is
also connect oriented.
