OpenBSD has had it since forever [1]. Why is such an obvious feature only reaching Linux now?

>OpenBSD has had it since forever.

OpenBSD introduced mimmutable in OpenBSD 7.3, which was released 10/4/2023 (for US people, it would be 4/10/2023), so it isn't "forever".

Meanwhile Linux and FreeBSD has "memfd_create" forever while OpenBSD doesn't have anonymous files and relies on "shm_open".

Correct but they did have a very similar syscall for a long time that they deprecated after the release of mimmutable iirc
