[RFC PATCH v1 06/16] vsock/virtio: remove record size limit for SEQPACKET

From: Arseny Krasnov
Date: Mon Jun 28 2021 - 06:03:15 EST


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).
