From: Cornelia Huck Commit fa1a8c23eb7d3ded8a3c6d0e653339a2bc7fca9e intended to introduce uevent suppression for subchannels, but half of it was lost somewhere. Now, we end up with two uevents for every registered subchannel :( So we should better add the missing part from http://marc.info/?l=linux-kernel&m=117515953113974&w=2.
