Subject: [RFC PATCH v2 5/6] virtio/vsock: remove record size limit for SEQPACKET
Date: Sun, 4 Jul 2021 11:10:52 +0300	[thread overview]
Message-ID: <20210704081055.89685-1-arseny.krasnov@kaspersky.com> (raw)
In-Reply-To: <20210704080820.88746-1-arseny.krasnov@kaspersky.com>

Remove record size limit which was 'peer_buf_alloc' value.
New approach doesn't need this, because data is copied to
user's buffer in stream manner(we don't wait until whole
record is received).
