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.
