This is the second part of the scsi_debug updates implementing ZBC support on top of Doug "per_host_store+random parameters, compare" patch series. The ZBC emulation implemented allows to emulate both host-managed and host-aware disks with configurable zone size, number of conventional zones znd maximum number of open zones. One feature missing is the emulation of ZBC RC_BASIS which changes the behavior of the READ CAPACITY command. This is however not a critical point for testing as, to my knowledge, there are no disks using RC_BASIS on the market today. RC_BASIS emulation can thus be added as a later patch. The emulated devices, both host-aware and host-managed, pass libzbc ZBC conformance tests (SG interface) as well as zonefs tests (block layer interface).
