ioctl's tend to be a horrid mess both for things like compat.but also for things like system call tracing and filtering (ie BPF).
The compat mess is fixable by making sure you always use 64-bit fields rather than pointers everywhere and everything is aligned. The tracing and filtering one not so much.
