[PATCH RFC v2 0/2] fuse: compound commands

[Horst Birthelmer]

In the discussion about open+getattr here [1] Bernd and Miklos talked
about the need for a compound command in fuse that could send multiple
commands to a fuse server.
    
Here's a propsal for exactly that compound command with an example
(the mentioned open+getattr).
