Like I said to you earlier today, it's not just what you claim it is.
You're splitting enable into atomic_pre_enable and atomic_enable, and
disable into atomic_disable and atomic_post_disable.

At the *very* least this should be explained in your commit log, and it
would be much better if it was done in another patch.
