This is normal.
To me, this was a bit crazy so I removed all of that and implemented a collection.
For what? list is a collection, and does not require reallocations on additions. Reallocations can fail.
Ever heard on IOCTL code collisions? if you will implement some IOCTL on a real device, then you can collide with another vendor’s code.
So, make your own CDO with a GUID-based name, and send all IOCTLs there (and only there).
