Subject: [PATCH v7 11/12] NFS handle COPY ERR_OFFLOAD_NO_REQS
Date: Tue, 20 Feb 2018 11:42:23 -0500 [thread overview]
Message-ID: <20180220164224.65366-12-kolga@netapp.com> (raw)
In-Reply-To: <20180220164224.65366-1-kolga@netapp.com>
If client sent async COPY and server replied with
ERR_OFFLOAD_NO_REQS, client should retry with a synchronous copy.
