Hi Sam,
Linux headers are imported into QEMU using
scripts/update-linux-headers.sh. Did you import the header using this
script?

If yes, please mention it in the commit description. If not, please do
so in the next revision.

Thanks,
Stefan

Yes, I'll change the commit description to "include: update virtio-blk
header from Linux 5.19-rc2+".
