He does mention Reiser5 in his letter:
> I don’t know what is in Reiser 5—I haven’t been told, and I cannot go on the Internet. Edward Shishkin is a very bright man though, and one of my regrets is that I didn’t spend more time with him, I am confident he has done some thing nice in Reiser 5.
https://www.phoronix.com/news/Reiser5-Development is the last reference I find to Rieser5, but the link in it goes to what appears to just be Reiser4 maintained against moderately recent kernels.
