Thx for the feedback. This is a great sentence to add at the end of the first paragraph instead of the link. I'll add it with a few changes as there are more than just one register function and the use of ARRAY_SIZE is implicit most of the time. This is now safe because the sysctl registration code (register_sysctl() and friends) use the array size in addition to checking for a sentinel.
