That's for streaming data between kernel and userspace.
What I'm doing is streaming from a filesystem on hard disk, which has
nothing to do with relayfs, and everything to do with the kernel's
file cache / readahead / reclamation heuristics, including
page_alloc{2}.c and kswapd.

I don't really understand that paragraph. Can you explain? Does it
have anything to do with streaming data from a disk filesystem?
