Hi: This series tries to implement tx batching support for vhost. This was done by using MSG_MORE as a hint for under layer socket. The backend (e.g tap) can then batch the packets temporarily in a list and submit it all once the number of bacthed exceeds a limitation. Tests shows obvious improvement on guest pktgen over over mlx4(noqueue) on host: Mpps -+%

Former logic of ocfs2_file_aio_write() was a bit stricky to unlock the rw_lock and i_alloc_sem, by using some private bits in struct 'iocb' to communite with ocfs2_dio_end_io(), it did work before we introduce the patch of supporting 'coherency=full,buffered' option, since rw_lock and i_alloc_sem were never acquired both at the same time, no mattar we doing buffered or direct IO or
