Both vfs_getattr and i_op->fsync return error statuses which nfsd was largely ignoring. This as noticed when exporting directories using fuse. This patch cleans up most of the offences, which involves moving the call to vfs_getattr out of the xdr encoding routines (where it is too late to report an error) into the main NFS procedure handling routines. There is still a called to vfs_gettattr (related to the ACL code) where the status is ignored, and called to nfsd_sync_dir don't check return status either.
