Try running an original MCC Linux binary and C lib on a current kernel We've put *entire binary formats* behind a config option. We've put older syscalls behind it, we've put sysfs behind it, sysctl behind it, the older microcode interfaces behind it, ISA bus as a concept behind options. VDSO, IPC, even 32bit support ... the list goes on and on. I'd say those were far more generic on the whole than splice/sendfile.
