A better description of what exactly you mean here (like what's LOMAC?)
would be very nice to try to examine your code to see if it matches up
with your documentation (as you have no documentation now, it's pretty
hard to see the big picture.)

And you do know that Linux has "EVMS" already, which this is bound to
get confused with...
