PCI: add rescan to /sys/.../pci_bus/.../
After remove the device from /sys, we have to rescan all or find out the bridge and access /sys../device/rescan there. this patch add /sys/.../pci_bus/.../rescan. So user can rescan more easy. that is more clean and easy to understand. like after remove 0000:c4:00.0, you can rescan 0000:c4 directly. -v2: According to Jesse, use function instead of exposing attr, so could hide #ifdef in header file. also add code to remove rescan file in remove path. -v3: GregKH pointed out that we should use dev_attrs to avoid racing. So add pcibus_attrs and make it to be member of pcibus_attrs. -v4: Change name to pcibus_dev_attrs according to GregKH Acked-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Yinghai Lu <yinghai@kernel.org> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
