Merge git://git.linux-nfs.org/pub/linux/nfs-2.6
* git://git.linux-nfs.org/pub/linux/nfs-2.6: NFSv4: handle lack of clientaddr in option string NFSv4: debug print ntohl(status) in nfs client callback xdr code SUNRPC: Clean up the sillyrename code NFS: Introduce struct nfs_removeargs+nfs_removeres NFS: Use dentry->d_time to store the parent directory verifier. SUNRPC: move bkl locking and xdr proc invocation into a common helper NFSv4: Fix the nfsv4 readlink reply buffer alignment NFSv4: Fix the readdir reply buffer alignment NFSv4: More NFSv4 xdr cleanups NFSv4: Try to recover from getfh failures in nfs4_xdr_dec_open NFSv4: 'constify' lookup arguments. NFSv4: Don't fail nfs4_xdr_dec_open if decode_restorefh() failed NFSv4: Fix open state recovery NFSD/SUNRPC: Fix the automatic selection of RPCSEC_GSS
