Still not quite there, but should be a bit more correct than the first RFC.
I still need to add proper error handling, the rest of block-queue itself
should be fairly complete. With respect to error handling, IDE, virtio-blk and
scsi-disk can deal with failed bdrv_(aio_)flush now, so just failing the next
flush seems to be a viable option now.
The integration into block.c and qcow2 is only a preliminary hack for now and
is going to be replaced.
Kevin Wolf (4):
block: Fake a bdrv_aio_pwrite
Add block-queue
Test cases for block-queue
qcow2: Use block-queue
