As a frequent user of git blame, I kinda agree with it.

That said, zswap functions ordering hurts my brain a lot. So I vote
for the reordering, and for paying the price sooner rather than later.
The alternative is reordering sometimes in the future (which is just
delaying the pain), or never re-order at all (which sucks).
