Subject: [PATCH 0/2] enable append-emulation for ZNS

Currently NVMe driver rejects the ZNS device if zone-append is not
supported natively.
Make it accept the device and activate append-emulation instead. This
is mostly borrowed from SCSI emulation.
The other patch enforces a zone-friendly I/O scheduler for ZNS.

Kanchan Joshi (2):
  nvme: set io-scheduler requirement for ZNS
  nvme: add emulation for zone-append
