At least one year, our 4.14 kernel does not include this option into the defconfig, 4.4 includes it, but probably we don't need it. > What about the other goldfish drivers? There are only four goldfish divers we use in R: goldfish_pipe, goldfish_battery, goldfish_sync and goldfish_address_space. The goldfish_battery one is fully upstreamed but I need to cleanup Kconfig's (this is why I sent this patch). The goldfish_pipe one has off-tree changes. The goldfish_sync and goldfish_address_space are not in the kernel tree at all. The rest can be retired - I will send patches. The goldfish_pipe driver will be replaced by virtio-vsock and virtio-console eventually. We considered retiring goldfish_battery by switching to ACPI_BATTERY but ACPI is not available (at least in GKI) on arm64. Regards, Roman.
