Hi Petr,

For the example you've given (Dragonfly section):

        long_return = proc_table[LowProcIndex].kp_eproc.e_uticks +
            proc_table[LowProcIndex].kp_eproc.e_sticks +
            proc_table[LowProcIndex].kp_eproc.e_iticks;

becomes:

        long_return = proc_table[LowProcIndex].kp_lwp.kl_uticks +
            proc_table[LowProcIndex].kp_lwp.kl_sticks +
            proc_table[LowProcIndex].kp_lwp.kl_iticks;

Check out http://fxr.watson.org/fxr/source/sys/kinfo.h?v=DFBSD#L145
for any other conversions you might need to do.

It looks like corecode and tgen changed the proc stuff about 3 months ago.
