Subject: [RFC PATCH v3 2/6] virtio/vsock: add 'VIRTIO_VSOCK_SEQ_EOR' bit.
Date: Mon, 16 Aug 2021 11:51:23 +0300	[thread overview]
Message-ID: <20210816085126.4173978-1-arseny.krasnov@kaspersky.com> (raw)
In-Reply-To: <20210816085036.4173627-1-arseny.krasnov@kaspersky.com>

This bit is used to handle POSIX MSG_EOR flag passed from
userspace in 'sendXXX()' system calls. It marks end of each
record and is visible to receiver using 'recvmsg()' system
call.
