In general, the right answer is to do the file handling in userspace. Among other things, that makes it possible to avoid hard-coding a filename in kernel code (remember - we try to make the kernel be about mechanism, not policy). Among other things, it avoids the effort of opening a file that userspace never actually does anything with - if you wait for userspace to open it and notify the kernel, you can be pretty sure that it's about to be used.
