Hi all,
This is v3 of the pci_slot patch series.
The major change is making the ACPI-PCI slot driver a Kconfig
option, as per the recommendations of others (Gary, Kenji-san).
Alex, What I was trying to suggest is a boot-time kernel option,
not a kernel configuration option. The basic idea is to give
the user (with a single binary kernel) the ability to include
your ACPI-PCI slot driver feature changes only when they are
really needed. In addition to reducing the number of
system/PCI hotplug driver combinations where your changes
would need to be validated, I believe would also help
alleviate other worries (e.g. Andi Kleen's memory consumption
concern). I believe this goal could also be achieved with the
kernel config option by making the pci_slot module runtime
loadable with the PCI hotplug drivers only visiting your new
code when the pci_slot driver is loaded, although I think this
would be more difficult to implement.
I agree to Gary very much.
Thanks,
Kenji Kaneshige
