Meh, that's true of some C projects, but AFAIK Linux/Redis have good reasons here, and if I were to criticize Linux for something, it wouldn't be unwillingness to write more code. I still prefer to evaluate each decision on its merits. Linux has made some great decisions. Also some terrible ones—e.g. fsync semantics [1], attitude to fuzzing. Redis probably has too. They can agree on something and be wrong. [1] https://wiki.postgresql.org/wiki/Fsync_Errors https://wiki.postgresql.org/wiki/Fsync_Errors
