It appears the bcachefs codes uses zero length It looks like this series hasn't been in -next at all? That seems like a pretty important step. Also, when I look at the PR, it seems to be a branch history going back _years_. For this kind of a feature, I'd expect a short series of "here's the code" in incremental additions (e.g. look at the x86 shstk series), not the development history from it being out of tree -- this could easily lead to ugly bisection problems, etc. -Kees -- Kees Cook
