The patchset is started while we try to address double remove pci devices via sysfs that is found by Gu. main point is from Bjorn that add reference for bus, and he also pointed out that release should be done in pci_release_device. After reviewing the add and remove path, found more problem that need to be addressed, like 1. proc attach/detach is not balanced 2. stop_and_remove device is not multiple calling safe. Also found sriov VFs add path has problem, it call pci_bus_add_device to early, and it will make VF's driver get probed before PF's driver probing is done. That will also have nested lock problem. Please consider those patches to be 3.10 materials. Thanks Yinghai PCI: move back pci_proc_attach_devices calling PCI: move resources and bus_list releasing to pci_release_dev PCI: Detach driver in pci_stop_device PCI: Fix racing for pci device removing via sysfs PCI, ACPI: Don't glue ACPI dev with pci VFs PCI: Make sure VF's driver get attached after PF's PCI: use pf as dma_dev for vf that does not have func0 sibling -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
