From a purist point of view, all these 'new' calls are generalizations of the existing ones taking an extra pid argument, so they can just replace them, with the old ones provided by the C library; of course in the real world there is such a thing as backward compatibility :-p.

Yeah, breaking the entire installed base of Linux apps would probably be a
*bad* move :) I think, if you wanted to do this, you'd have to introduce a huge pile of new syscalls and reimplement the old ones as thin wrappers (inside the kernel so as not to force everyone to upgrade glibc) calling the new ones.

This is analogous to the *at system calls (openat, fstatat, ...) that have been introduced in Linux and included in the latest revision of POSIX.
