If I understand the sysctl logic correctly, the .maxlen is the maxlen of
the input to the sysctl, and not the data. Usually set to sizeof(data)
because most proc_handlers write to data directly.
In this case, I believe it's not even used (you override it with the
struct ctl_table tmp). I guess it doesn't really matter what it's set to.
Perhaps just set it to zero and leave it out?

Same here.
