Do we want to pass flags to bdrv_co_do_copy_on_readv(), too? I guess we would use them for the preadv call there, but continue to use 0 as the pwritev flags. We may also want to introduce a .supported_read_flags, but perhaps this is not something to do in this patch. And we don't even use .supported_write_flags for drivers that have a native .bdrv_co_pwritev. Of course, that's even less related to this patch. I guess I should send a fix for that. Looks good otherwise. Kevin
