Yes the idea would be a special-purpose allocater thing like ion. Might even want that to be a syscall to do it properly.

Would you care to elaborate why a syscall would be more proper? Not that I'm objecting to it, just for my education.

It seems to be the theme with someone proposing a global /dev node for a few system wide ioctls, then reviewers ask to make a proper ioctl out of it. E.g. kdbus, but I have vague memory of this happening a lot. -Daniel
