Unfortunately the diff is deceiving. I just posted the diff that
adds the new functionality to the code, but not the part to provide
backwards compatibility. There 100's of lines of code in the compat
glue just to handle the old syscalls both in libc and the kernel.
The real issue though is what happens if you don't put the
functionality where it belongs; look what has happened to the linux
statvfs syscall family for example and the answers to the question
how do I get the mountpoint of a particular file, or how do I get
the list of mountpoints etc.

I still think that it is better to design good software interfaces
as opposed to resorting to procfs/sysctl/ioctl or whatever glue to
gather information even when the compat cost is high.
