From 0491567b51efeca807da1125a1a0d5193875e286 Mon Sep 17 00:00:00 2001 From: Olga Kornievskaia Date: Tue, 4 Jun 2019 16:14:30 -0400 Subject: NFS: add COPY_NOTIFY operation 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.
