Merge branch 'nfs-for-2.6.39' of git://git.linux-nfs.org/projects/trondmy/nfs-2.6
* 'nfs-for-2.6.39' of git://git.linux-nfs.org/projects/trondmy/nfs-2.6: (28 commits) Cleanup XDR parsing for LAYOUTGET, GETDEVICEINFO NFSv4.1 convert layoutcommit sync to boolean NFSv4.1 pnfs_layoutcommit_inode fixes NFS: Determine initial mount security NFS: use secinfo when crossing mountpoints NFS: Add secinfo procedure NFS: lookup supports alternate client NFS: convert call_sync() to a function NFSv4.1 remove temp code that prevented ds commits NFSv4.1: layoutcommit NFSv4.1: filelayout driver specific code for COMMIT NFSv4.1: remove GETATTR from ds commits NFSv4.1: add generic layer hooks for pnfs COMMIT NFSv4.1: alloc and free commit_buckets NFSv4.1: shift filelayout_free_lseg NFSv4.1: pull out code from nfs_commit_release NFSv4.1: pull error handling out of nfs_commit_list NFSv4.1: add callback to nfs4_commit_done NFSv4.1: rearrange nfs_commit_rpcsetup NFSv4.1: don't send COMMIT to ds for data sync writes ...
