Note: the virtio-blk headers isn't upstream in the kernel yet therefore
marked as an RFC. The VIRTIO spec changes have been merged. The Linux
virtio_blk guest driver patches are in Michael Tsirkin's vhost tree:
https://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost.git/tree/drivers/block/virtio_blk.c?h=vhost
v6:
- address Stefan's review comments
* add accounting for zone append operation
* fix in_iov usage in handle_request, error handling and typos
v5:
- address Stefan's review comments
* restore the way writing zone append result to buffer
* fix error checking case and other errands
v4:
- change the way writing zone append request result to buffer
- change zone state, zone type value of virtio_blk_zone_descriptor
- add trace events for new zone APIs
v3:
- use qemuio_from_buffer to write status bit [Stefan]
- avoid using req->elem directly [Stefan]
- fix error checkings and memory leak [Stefan]
v2:
- change units of emulated zone op coresponding to block layer APIs
- modify error checking cases [Stefan, Damien]
v1:
- add zoned storage emulation
Sam Li (4):
include: update virtio_blk headers
virtio-blk: add zoned storage emulation for zoned devices
block: add accounting for zone append operation
virtio-blk: add some trace events for zoned emulation
