Abstract: Windows File Protocols: it's a love/hate relationship.
                We wish we could leave them behind, but we know we
                never will. Some of us even dream about them at night,
                so we know we have to take a good hard look at the
                relationship and figure out how to make it work.

                This presentation will go into features of the SMB3
                protocol, particularly those that are important to--
                and have an impact on--Linux kernel development.
                Things like the relationship between SMB OpLocks and
                Linux kernel leases, the semantics of Access Control
                Lists, and details of the distributed caching system
                introduced with Windows 7 and 8.

Attendees: Much of this focuses on local file systems. The
                distributed caching system, for instance, should be
                connected with the file system cache on the client
                side. On the server side, the dedupe algorithms in
                BtrFS could be leveraged, but we also need a place
                to store block hashes that are in sync with the data.
                Anyone working with kernel leases should find the
                semantic differences between those and OpLocks of
                interest.

Biohazard: Chris Hertel is a medium-size ruminant mammal (Geekus
                geekus) with long legs, humped shoulders, and broadly
                palmated antlers. He is a long-haul Samba Team member,
                author of "Implementing CIFS", and lead author (under
                contract) of Microsoft's official SMB/CIFS (SMBv1)
                specifications (freely available for download).

                Chris has been Adjunct Faculty at the University of
                Minnesota, where he is now a member of the advisory
                board for the College of Continuing Education's
                Information Technology Infrastructure program.

                Chris currently holds court as Senior Principal
                Software Engineer at Red Hat, working from their
                offices in a quaint suburb of Saint Paul, MN.
