Ok, Trying once more. After spending a couple of hours trying to follow the QEMU dma codeflow, I have convinced myself Avi is right and those two functions don't need to do the flushing as they all end up calling dma_bdrv_cb() which calls dma_brdv_unmap(). I have added a couple comments to the code, which will hopefully save the next person the 'pleasure' of trying to figure out this too.
It looks right to me. Xiantao?
access_len -= l;

+ dma_flush_range((unsigned long)buffer,

Detab your code, please. -- error compiling committee.c: too many arguments to function -- To unsubscribe from this list: send the line "unsubscribe kvm-ia64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
