[PATCH pynfs v2 00/16] prep for flex file layout server

[Weston Andros Adamson <dros@primarydata.com>]

Changes in v2:

 - moved "4.1 client: reclaim_complete after create_session" to
   "dataserver: reclaim_complete after create_session" as the implicit
   reclaim complete is needed in DS path, but not in all server tests.

 - dropped "4.1 server: service RECLAIM_COMPLETE operations" as it's
   unneeded.

 - formatted these patches with -M flag so we can see moved files

.. and I pushed the changes to my ff_prep branch.

Thanks!

These patches are in preparation for the pynfs implementation of a flex
file layout server.

I already have patches for a working flex file server, but I figure those
should wait until the spec is complete ;)

I pushed these patches to my linux-nfs.org tree on branch 'ff_prep':

 git://git.linux-nfs.org/projects/dros/pynfs.git

The prep includes:

 - patches that enable pynfs mds using real v4.1 DSes (on the backend,
   not usable from clients as there is no stateid sharing between mds and ds)

 - fix several bugs in pnfs path

 - move .x files to subdir 'xdrdef' - the nfs4.1 directory was getting crowded
   and we're going to add several more .x files along with all of the
   autogenerated files.  Note this change touches server tests too.

 - clean up the nfs4server's output - no longer print out EVERY part of EVERY
   operation which was very efficient at hiding tracebacks and made pynfs
   even slower. Old functionality is now switched on with -v flag. Also
   added an in-between mode "-s" that prints a summary of whats going on.

 - support for NFSv3 backend communication - this is not actually used yet,
   but can be tested with file layout by always returning
   NFS4ERR_LAYOUTUNAVAILABLE in layoutget and using DataServer3 class instead
   of DataServer41
