Speeding up Linux disk encryption (Cloudflare)

The Cloudflare blog has an article on the company's work to improve the performance of Linux disk encryption. "As we can see the default Linux disk encryption implementation has a significant impact on our cache latency in worst case scenarios, whereas the patched implementation is indistinguishable from not using encryption at all. In other words the improved encryption implementation does not have any impact at all on our cache response speed, so we basically get it for free!" Patches are available, but they are apparently not in any form to go upstream.
