Looks like this is a thin translation layer for BeOS/Haiku syscalls. I wonder why they aren't relying on Syscall User Dispatch https://docs.kernel.org/6.19/admin-guide/syscall-user-dispat... which would enable them to put this compatibility layer in user space. It's already being used by recent Wine versions.

It's not really a translation layer, nexus implements the same BeOS/Haiku IPC in kernel but using linux kernel primitives. It's not as much as a translation layer than any other IPC in the linux system, really BeOS/Haiku apps are first class citizens.

Most of BeOS IPC is in mainline Linux kernel [1] - the difference here seems to be implementing some of the services that are supposed to be available related to filesystem etc and the user land side of it (raw IPC does very little without another layer on top)

[1] - there's a reason why a bunch of BeBook reads the same as some of the oldest parts of Android documentation
