Ok, thanks for clarifying. > The same is true for the ipc system call. (any reason why the seperate system > calls haven't been enabled on x86 now as well?) Agreed, we should split that out on all architectures as well. Almost the same set of architectures that have sys_socketcall also have sys_ipc, and the reasons for changing are identical. I don't think we have any other system calls that are handled like this on some architectures but not on others. There are a couple of system calls (e.g. futex) that are also multiplexers, but at least they do it consistently. Arnd
