NFS client behavior on WRITE_DELEGATION

[Soumya Koduri <skoduri@xxxxxxxxxx>]

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
