In the recent pnfs kernel versions, WRITE operation will not send LAYOUTCOMMI OP to MDS if use filelayout. In nfs_write_rpcsetup function, the value of the variable 'stable' will always be NFS_FILE_SYNC(ncommit is 0). so NFS_INO_LAYOUTCOMMIT flag will not be set. The value of the variable ncommit' will be ++ in the later process (nfs_writeback_release_common function).
