Hi Bjorn, Hi Jan, In an earlier version[0], I sought to apply the existing jailhouse special case for isolated PCI functions to s390. As Bjorn noted in[1] there appears to be some potential for cleaning things up and removing duplication though. This series attempts to do this cleanup (Patches 1 and 2) followed by enabling isolated PCI functions for s390 (Patches 3 and 4). If need be I can of course split the cleanup off but for now I kept it as one as that's what I have been testing. Thanks, Niklas Changes v2 -> v3: - Removed now unused nr_devs variable (kernel test robot) [0] https://lore.kernel.org/linux-pci/20220404095346.2324666-1-schnelle@xxxxxxxxxxxxx/ [1] https://lore.kernel.org/linux-pci/20220408224514.GA353445@bhelgaas/ Niklas Schnelle (4): PCI: Clean up pci_scan_slot() PCI: Move jailhouse's isolated function handling to pci_scan_slot() PCI: Extend isolated function probing to s390 s390/pci: allow zPCI zbus without a function zero arch/s390/pci/pci_bus.c | 82 ++++++++++---------------------------- drivers/pci/probe.c | 63 +++++++++++------------------ include/linux/hypervisor.h | 9 +++++ 3 files changed, 52 insertions(+), 102 deletions(-) -- 2.32.0
