There isn't a one-to-one correspondence between a bullet and a change in the code. Breaking the rewrite into small pieces would not only be quite hard but to some extent even more confusing to audit since you risk to see the leaves instead of the tree.

We've done this before.  We can help you break it apart.

Step 1: Change all the existing spinlocks to spin_lock_bh().
Step 2: Do all the white space changes.
Step 3: Shuffle the global variable declarations around.

That's half the patch gone already.
