The virtio_scsi driver enqueues buffers to the eventq but does not actually handle them on completion. The following events could be reported to the driver which require some action to be taken:

Although a new inline assembly syntax asm! was announced in Rust on 2020/06/08[1], KRaBs still uses llvm_am!.

[1] New inline assembly syntax available in nightly

According to the blog, the asm! macro should be safer and easier to use. This is expected to become the mainstream of inline assembly in the future, so

the binary memory map describes only one space, starting with the physical address 0x00100000
process the rest of the memory map entries and describe them in a binary memory map
