ID is the kernel value in the xarray - xarray is much more efficient &
safe with small kernel controlled values.

dev_cookie is a user assigned value that may not be unique. It's
purpose is to allow userspace to receive and event and go back to its
structure. Most likely userspace will store a pointer here, but it is
also possible userspace could not use it.

It is a pretty normal pattern
