NFS client behavior on WRITE_DELEGATION

Hi,

In our NFSv4.1 Delegations testing we observed that NFS client sends
WRITE requests to the server even when granted WRITE_DELEGATION. I see
that only OPEN/CLOSE and LOCK operations are served locally by the client.

Please confirm if this behavior is expected and if yes, can it be
improved to avoid sending WRITEs to the server until the application
does fsync.

Thanks,
Soumya
