Right, that's correct. Ezequiel will expand on this, but we
intentionally excluded the cases we couldn't test, such as 2048 bytes
page size.

We were just waiting for people to have practical cases that we can
test, so I'm sure Ezequiel will provide patches to support 2048 bytes
page size.

Thanks for your testing, very useful!
