I think it is clearer to just say:

Move from register_net_sysctl() to register_net_sysctl_sz()

That is not as clear. I think you should just spell it out.

We want to use the syctl ARRAY_SIZE() when possible, and subsequent
patches ... now the register_net_sysctl() <does something> while
register_net_sysctl_sz() <does something else> and <in this case>
this user <does something> and so we must use register_net_sysctl_sz().
