My original suggestion, which is straight forward to implement, is to just store the fp in each of the devfs_fo_* operations somewhere (e.g. curthread like FreeBSD, although that isn't all that nice), and then clean it up on devfs_fo_close. Having that, you can easily implement the rest to set up some list or tree or whatever inside a cdev that is also passed to the function. the search key would then be the fp that you stored somewhere whilst in devfs_fo_*.
