Driver core: add missing kset uevent
We get uevents for a bus/class going away, but not one registering. Add the missing uevent in kset_register(), which will send an event for a new bus/class. Suppress all unwanted uevents for bus subdirectories like /bus/*/devices/, /bus/*/drivers/. Now we get for module usbcore: add /module/usbcore (module) add /bus/usb (bus) add /class/usb_host (class) add /bus/usb/drivers/hub (drivers) add /bus/usb/drivers/usb (drivers) remove /bus/usb/drivers/usb (drivers) remove /bus/usb/drivers/hub (drivers) remove /class/usb_host (class) remove /bus/usb (bus) remove /module/usbcore (module) instead of: add /module/usbcore (module) add /bus/usb/drivers/hub (drivers) add /bus/usb/drivers/usb (drivers) remove /bus/usb/drivers/usb (drivers) remove /bus/usb/drivers/hub (drivers) remove /class/usb_host (class) remove /bus/usb/drivers (bus) remove /bus/usb/devices (bus) remove /bus/usb (bus) remove /module/usbcore (module) Signed-off-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
