But more importantly does any of the memory pools code actually make a difference in benchmarks? What is the difference between running with OZ_MAX_TX_POOL_SIZE as zero and it set to 6?
Agree. Thats is a good test to look for.
We have this very complicated code with spinlocks and linked lists to save six 56 byte allocations... It's silly. :P Just use kmalloc().
Probably we will need to kmalloc() & kfree() few hundred times every second when data transfer is taking places. By maintaining a pool of 6, we avoid calling kmalloc frequently. Although I agree that some benchmarking is required here to verify that we actually get some advantage with current implementation.
