Hi Sam and Klaus, Val is adding nvme-io_uring ZNS support to libblkio (https://gitlab.com/libblkio/libblkio/-/merge_requests/221) and asked how to test the size of the last zone when the namespace's total size is not a multiple of the zone size.
My understanding is that the zoned storage model allows the last zone to be smaller than the zone size in this case. However, the NVMe ZNS emulation code in QEMU makes all zones a multiple of the zone size. I think QEMU cannot be used for this test case at the moment. Are there any plans to allow the last zone to have a different size? Maybe Sam's qcow2 work will allow this? Thanks, Stefan
