The main problem that ksm will face when removing the fd interface is:
right now when you register memory into ksm, you open fd, and then ksm

Did you test whenever it really cleans up in case you "kill -9 qemu"?
I recently did something simliar with the result that the extra
reference hold on mm_struct prevented the process memory from being
zapped ...

Did you use mmput() after you called get_task_mm() ???
get_task_mm() do nothing beside atomic_inc(&mm->mm_users);
and mmput() do nothing beside dec this counter and check if no reference
are available to this....
Am i missing anything?
