Hi,

We already have bdrv_aio_readv/writev which currently linearize the
buffer underneath.  Hopefully Anthony will have commited the patch to
implement the real one while I'm writing this, too :)

Is there any specific reason to keep the nb_sectors argument forbdrv_aio_readv, other than cut&paste from the non-vectored versions?I think it is superfluous now, it can be trivially calculated usingiov->size.


cheers,
  Gerd
