12 1. Block layer APIs for zoned storage
14 QEMU block layer supports three zoned storage models:
15 - BLK_Z_HM: The host-managed zoned model only allows sequential writes access
18 - BLK_Z_HA: The host-aware zoned model allows random write operations in
20 - BLK_Z_NONE: The non-zoned model has no zones support. It includes both
28 zoned storage information can be propagated from the leaf BlockDriverState all
29 the way up to the BlockBackend. If the zoned storage model in file-posix is
30 set to BLK_Z_HM, then block drivers will declare support for zoned host device.
