On embedded systems, we had audio streaming or CAN communication or similar
running in parallel. Currently, those mdelays (there are a couple, sadly)
produce significant latencies, e.g. when inserting/removing a card. The latter
gets especially bad with BROKEN_CARD_DETECTION.

The proper solution is probably to check the locking and see if it can be made
fine-granular, I'd assume?
