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.
replyIt'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.
