[Qemu-devel] [PATCHv2 0/6] multiwrite patches for 2.2

[Peter Lieven]

This adds some preparing patches for upcoming multiwrite modifications.
I will leave the dangerous patches for after 2.2 release.

v1->v2: - incorporated Max's comments, but did not display the default
          value for write merging (Patch 3) in the HMP since we do not
          do it for other commands. I would change this when the default
          changes.
        - added an iotest for the write-merging cmdline parameter [Max]
        - fixed iotest 067 output

Peter Lieven (6):
  block: add accounting for merged requests
  block: introduce bdrv_runtime_opts
  block: add a knob to disable multiwrite_merge
  hw/virtio-blk: add a constant for max number of merged requests
  block: add qemu-iotest for write-merge parameter
  block: fix qemu-iotest reference output for test 067
