    Merge branch 'for-3.9' of git://linux-nfs.org/~bfields/linux · b6669737

    Pull nfsd changes from J Bruce Fields:
     "Miscellaneous bugfixes, plus:
    
       - An overhaul of the DRC cache by Jeff Layton.  The main effect is
         just to make it larger.  This decreases the chances of intermittent
         errors especially in the UDP case.  But we'll need to watch for any
         reports of performance regressions.
    
       - Containerized nfsd: with some limitations, we now support
         per-container nfs-service, thanks to extensive work from Stanislav
         Kinsbursky over the last year."
    
    Some notes about conflicts, since there were *two* non-data semantic
    conflicts here:
    
     - idr_remove_all() had been added by a memory leak fix, but has since
       become deprecated since idr_destroy() does it for us now.
    
     - xs_local_connect() had been added by this branch to make AF_LOCAL
       connections be synchronous, but in the meantime Trond had changed the
       calling convention in order to avoid a RCU dereference.
    
    There were a couple of more obvious actual source-level conflicts due to
    the hlist traversal changes and one just due to code changes next to
    each other, but those were trivial.
