More "store" questions

[Galchin Vasili]

Hello,

   1) In the network block device client, nbd.c, it 
       seems very reasonable to set the "handle" on a 
       request and match this "handle" when receiving 
       a reply. It doesn't seem like it is set. Is 
       this because you have not implemented the 
       notion of queued requests in nbd.c, i.e. 
       handles definitely make sense when there are
       several outstanding requests.

   2) In ndbopen, where is the parameter "mod_flags" 
        set?

   3) You have defined a set of instances of "struct 
        store_class". What happens in the case where 
        not all "store" operations are defined, e.g. 
        store_part_class only defines open, not read, 
        write, etc.

   4) If I am writing a "store" server
         that can handle an arbitrary "name" (i.e. 
         I can't make an assumptions ahead of time 
          about the syntax of "name", i.e. I don't 
          in advance the type of store), what to I 
          call from my server to invoke the correct
          libstore functionality?

   5) I still don't understand the purpose of the 
        decode and encode functionality.
