A new version of I-D, draft-hildebrand-nfsv4-fadvise-01.txt has been 
successfully submitted by Dean Hildebrand and posted to the IETF repository.

Filename:          draft-hildebrand-nfsv4-fadvise
Revision:          01
Title:             Support for posix_fadvise
Creation_date:     2011-03-29
WG ID:             Independent Submission
Number_of_pages:   9

Abstract:
This document proposes a new FADVISE operation for NFSv4.2 to support
the posix_fadvise function.  FADVISE will communicate expected
application behavior to the server, allowing servers to optimize
future I/O requests for a file.  The posix_fadvise function is
supported in Linux and many other operating systems and is starting
be widely used by applications. In addition, the FADVISE operation
can communicate other application directions such as the use of
direct I/O.
-------------

As promised, here is an ID that allows NFS to support the POSIX fadvise 
operation as defined here:
http://pubs.opengroup.org/onlinepubs/009695399/functions/posix_fadvise.html

This ID also allows support for sending I/O access hints when a client 
uses direct I/O or at any other point when a client feels it could be 
useful.

This sets out the minimum number of client initiated *hints* to the 
server that we must support.  These hints can be extended as needed for 
other requirements.

Hope everyone had fun in Prague,

Dean
