rockbox/firmware/export/ata_idle_notify.h
Jonathan Gordon 31a4dc9caa undo the last commit... I'm too tired to fgure out how to make batt bench work without the spin down notification (aka, fix red the really lazy way)

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