You may already be running Linux v5.3! I'm excited about heap auto-initialization, pidfd_open(), global -Wimplicit-fallthrough, x86 CR4 & CR0 pinning, more kfree() sanity checks, arm64 default KASLR, and hardware security embargo documentation: https://outflux.net/blog/archives/2019/11/14/security-things-in-linux-v5-3/ …

Fixing warnings from "make htmldocs" is very needed. I've done tiny pieces of it and we recently had some big cleanups in security docs, but there is much more to be done. Getting there is important because then it's easier to maintain a 0-warnings build (as done for the code)https://twitter.com/lwnnet/status/1220484965667954689 …
