That commit would be called something like "pc: Support hv-balloon".
If I remove the driver from Kconfig in the initial patch then AFAIK
this initial patch will add a dead driver file that it is not possible
to build yet, right?
Yes, that's also what we did for virtio-mem:
(bottom to top)
0ed48fd32e pc: Support for virtio-mem-pci
16647a8224 numa: Handle virtio-mem in NUMA stats
2e70874b16 hmp: Handle virtio-mem when printing memory device info
751c7bdd04 MAINTAINERS: Add myself as virtio-mem maintainer
0b9a2443a4 virtio-pci: Proxy for virtio-mem
910b25766b virtio-mem: Paravirtualized memory hot(un)plug
And virtio-pmem:
(bottom to top)
a0a49813f7 pc: Support for virtio-pmem-pci
cae02c3480 numa: Handle virtio-pmem in NUMA stats
d766b22bbd hmp: Handle virtio-pmem when printing memory device infos
adf0748a49 virtio-pci: Proxy for virtio-pmem
9f583bdd47 virtio-pmem: sync linux headers
5f503cd9f3 virtio-pmem: add virtio device
As you're adding all in a single series, that's perfectly fine.
