We changed these sysfs filenames: .../pci_bus//rescan -> .../pci_bus//bus_rescan ...//rescan -> ...//dev_rescan and Ruslan reported [1] that this broke a userspace application. Revert these name changes so both files are named "rescan" again. Note that we have to use __ATTR() to assign custom C symbols, i.e., "struct device_attribute ".
