This is a series of RFC patches, to make sure we are doing the right thing in the right way. The patchset hasn't been tested yet. There are several minor bugfixes and two proposals. The first proposal is to add notification chain for PCI hotplug events, so other components interested in PCI root/bus/device hotplug events could subscribe to the chain. The second prososal is to introduce a recursive mutex lock to serialize all hotplug operations triggered by sysfs interfaces, PCI HPC hardware events, ACPI hotplug events and other sources. There are still works left in driver/pci/hotplug directory to apply the above two proposals. The patchset applies to Yinghai's work on PCI root bus hotplug at git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git for-x86-irq And it depends on my previous patchset, please refer to http://www.spinics.net/lists/linux-pci/msg14472.html Thanks!
