do you want to watch for disk i/o or file i/o ?
Ideally, disk I/O. If a cache hit satisfies a request, and I miss
that event, that's fine.
the below options should help you if you need to watch for file i/o,
but then will the hooking be implemented before the VNODE/VFS file
cache ?
I believe the approach I'm looking at now, Kauth, will miss requests
satisfied by the cache.
