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
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
