In short, I'd like 'divide and > conquer' method in code refactoring. I guess, you may show us some code for comments (just a prototype - no full implementation). As you noted, the separate allocations may save some space depending on the slab implementation, but it should not be the main reason for such changes. The device objects were added to the ALSA control stack later (they simply didn't exist when we designed it). Also, the low-level drivers communicate with the control layer using the card structure pointer. The additional translation is another challenge.
