    I recommend that instead of rolling these sorts of system calls over
    and over again (how many versions of stat do we have now?  A lot!),
    that instead you make a system call which returns a capability buffer
    and then have libc load the capabilities it understands into the
    structure.  That way you don't have to worry about forwards and 
    backwards kernel compatibility.

    This is what I plan to do with DragonFly for *stat(), *statfs*(), 
    various sysctls that return structures, and so forth.  Wherever it makes
    sense to do it.
