Merge branch 'for-2.6.31' of git://git.linux-nfs.org/projects/trondmy/nfs-2.6
* 'for-2.6.31' of git://git.linux-nfs.org/projects/trondmy/nfs-2.6: (128 commits) nfs41: sunrpc: xprt_alloc_bc_request() should not use spin_lock_bh() nfs41: Move initialization of nfs4_opendata seq_res to nfs4_init_opendata_res nfs: remove unnecessary NFS_INO_INVALID_ACL checks NFS: More "sloppy" parsing problems NFS: Invalid mount option values should always fail, even with "sloppy" NFS: Remove unused XDR decoder functions NFS: Update MNT and MNT3 reply decoding functions NFS: add XDR decoder for mountd version 3 auth-flavor lists NFS: add new file handle decoders to in-kernel mountd client NFS: Add separate mountd status code decoders for each mountd version NFS: remove unused function in fs/nfs/mount_clnt.c NFS: Use xdr_stream-based XDR encoder for MNT's dirpath argument NFS: Clean up MNT program definitions lockd: Don't bother with RPC ping for NSM upcalls lockd: Update NSM state from SM_MON replies NFS: Fix false error return from nfs_callback_up() if ipv6.ko is not available NFS: Return error code from nfs_callback_up() to user space NFS: Do not display the setting of the "intr" mount option NFS: add support for splice writes nfs41: Backchannel: CB_SEQUENCE validation ...
