Note: the virtio-blk headers isn't upstream in the kernel yet therefore
marked as an RFC.

v3:
- use qemuio_from_buffer to write status bit [Stefan]
- avoid using req->elem directly [Stefan]
- fix error checkings and memory leak [Stefan]

v2:
- change units of emulated zone op coresponding to block layer APIs
- modify error checking cases [Stefan, Damien]

v1:
- add zoned storage emulation

Sam Li (2):
  include: update virtio_blk headers from Linux 5.19-rc2+
  virtio-blk: add zoned storage emulation for zoned devices
