Subject: [PATCH v6 02/19] NFS: add COPY_NOTIFY operation
Date: Fri,  6 Sep 2019 15:46:14 -0400
Message-ID: <20190906194631.3216-3-olga.kornievskaia@gmail.com> (raw)
In-Reply-To: <20190906194631.3216-1-olga.kornievskaia@gmail.com>

From: Olga Kornievskaia <kolga@netapp.com>

Try using the delegation stateid, then the open stateid.

Only NL4_NETATTR, No support for NL4_NAME and NL4_URL.
Allow only one source server address to be returned for now.

To distinguish between same server copy offload ("intra") and
a copy between different server ("inter"), do a check of server
owner identity and also make sure server is capable of doing
a copy offload.
