I suspect on your system you don't have the cross function DB built so
it's not aware what happens in nvme_init_ctrl() or the other function I
mentioned.

On my system there is too much data so it isn't parsed.
1) When there is too much data it should just mark ctrl->ops as unknown
2) I should try to consolidate the data.  I should just mark all of
   ctrl->ctrl_device as unknown instead of recording any of the struct
   members individually.  There might also be stuff that isn't used like
   ctrl->namespaces_rwsem internals.
3) On my system, I have 2187 bogus entries that say we removed an item
   from a list.

Probably any of these fixes would silence the false positive but it
would be better to do all three.

If you don't have the cross function database though, you're probably
out of luck.  There are always going to be more false positives if you
don't have the cross function information.
