29 NOTE: storage_idle_notify usage notes..
31 1) The callbacks are called in the ata thread, not main/your thread.
32 2) Asynchronous callbacks (like the buffer refill) should be avoided.
33 If you must use an async callback, remember to check storage_is_active() before
34 accessing the disk, and do not call any functions between that check and the
35 disk access which may cause a yield (lcd_update() does this!).
36 3) Do not call any yielding functions in the callback.
37 4) Do not call storage_sleep in the callbacks.
38 5) Don't Panic!
