Please mark this symbol static (otherwise it's name pollutes the global
name space, "clean_acked" what?  for what subsystem? etc.)

And add two helper functions, icsk_clean_acked_enable() and
icsk_clean_acked_disable() which adjust the static key as
needed.

For the enable helper, you can pass in an icsk and the function
pointer, so that the helper can do the assignment and the
connection between the static key and registering on an icsk
is clear.
