this series adds the long missing multiread support to virtio-blk.
some remarks:
- i introduced rd_merged and wr_merged block accounting stats to
blockstats as a generic interface which can be set from any
driver that will introduce multirequst merging in the future.
- the knob to disable request merging is not yet there. I would
add it to the device properties also as a generic interface
to have the same switch on for any driver that might introduce
request merging in the future
- there is cleanup and iotest adjustion missing.
Peter Lieven (3):
block: add accounting for merged requests
hw/virtio-blk: add a constant for max number of merged requests
virtio-blk: introduce multiread
