I'm the only one who loves how Fengguang Wu does his kernel work? His changelogs are always very well detailed and give a lot of insight of what they do and why they do it.

That patch sounds nice, but has to be tested a lot to confirm it does what it should in every situation. It especially needs testing on lots of different systems with different storages, from USB sticks to big irons. I like the description of how everything is calculated, seems like the Right Approach.

Compressed RAM swap could also be an interesting test-case.

The differences to normal swap devices are:
- swapping causes CPU load, not IO load
- smaller than the amount of RAM instead of larger
