Merge git://git.linux-nfs.org/projects/trondmy/nfs-2.6
* git://git.linux-nfs.org/projects/trondmy/nfs-2.6: (70 commits) fs/nfs/nfs4proc.c: make nfs4_map_errors() static rpc: add service field to new upcall rpc: add target field to new upcall nfsd: support callbacks with gss flavors rpc: allow gss callbacks to client rpc: pass target name down to rpc level on callbacks nfsd: pass client principal name in rsc downcall rpc: implement new upcall rpc: store pointer to pipe inode in gss upcall message rpc: use count of pipe openers to wait for first open rpc: track number of users of the gss upcall pipe rpc: call release_pipe only on last close rpc: add an rpc_pipe_open method rpc: minor gss_alloc_msg cleanup rpc: factor out warning code from gss_pipe_destroy_msg rpc: remove unnecessary assignment NFS: remove unused status from encode routines NFS: increment number of operations in each encode routine NFS: fix comment placement in nfs4xdr.c NFS: fix tabs in nfs4xdr.c ...
