[Qemu-devel] [PATCH 0/4] block: Vectored bdrv_writev_vmstate

[Kevin Wolf]

This gives us back reasonable savevm performance, which regressed in
commit 500f0061.

Kevin Wolf (4):
  block: Introduce bdrv_writev_vmstate
  savevm: Implement block_writev_buffer()
  block: Introduce bdrv_pwritev() for qcow2_save_vmstate
  qemu-iotests: A few more bdrv_pread/pwrite tests
