Note that when you only have a copyright left in a header comment after removing the boilerplate, you might want to consider this even shorter and cleaner form instead.

AFAIK he is working on an updated version whenever his real time body clock yields a few ticks so he can wrap this out. But his real time clock only rarely yield ticks outside of hard real time coding work ;) Jonathan also wrote a nice background article on the topic at LWN [2]. I heard this was also briefly discussed among maintainers at the plumbers meetup in Los Angeles: for me I only briefly discussed this with Linus and Greg just before the meetup, but I could not stay longer. > should I make a similar push for the subsystems I > maintain? That would be great! And beside the fact it always feels good to delete lines of code for once, this is one of the rare areas where you can kill some lines and be pretty sure it will still compile and run afterwards .... well.... in most cases: Greg and Thomas found funny cases of .h headers included in assembly where using the // comment style was actually making things break weirdly and the compilation would go down in flames with a beautiful tail spin : in these cases, the convention is to use /**/ comments instead) Again, if you need help with this, I can modestly chip in with my scancode-toolkit tool and good intentions.
