This two-part series contains code fixes that are related to the recently added support for zoned block devices in virtio-blk driver. The original ZBD patchset that was merged to the kernel -next was not the latest and greatest version. The first patch of this series is essentially a diff between the current code and the final revision of the original patchset. The second patch fixes a problem that is observed when a host-managed zoned device is virtualized via virtio-blk and the driver kernel is configured without ZBD support (CONFIG_BLK_DEV_ZONED not set). In this case, the driver must not allow the device scan to succeed in order to avoid erroneous device operation that may cause data loss. The second patch adds this currently missing functionality. v1 -> v2: - address nits from Damien - add Review-by tags from Stefan and Damien Dmitry Fomichev (2): virtio-blk: migrate to the latest patchset version virtio-blk: fix ZBD probe in kernels without ZBD support drivers/block/virtio_blk.c | 269 ++++++++++++++++++++------------ include/uapi/linux/virtio_blk.h | 18 +-- 2 files changed, 182 insertions(+), 105 deletions(-) -- 2.34.1
