Subject: [PATCH v9 08/11] NFS: COPY handle ERR_OFFLOAD_DENIED
Date: Fri, 14 Jun 2019 16:00:13 -0400
Message-ID: <20190614200016.12348-9-olga.kornievskaia@gmail.com> (raw)
In-Reply-To: <20190614200016.12348-1-olga.kornievskaia@gmail.com>

From: Olga Kornievskaia <kolga@netapp.com>

If server sends ERR_OFFLOAD_DENIED error, the client must fall
back on doing copy the normal way. Return ENOTSUPP to the vfs and
fallback to regular copy.
