I was hoping someone else would do comprehensive disk benchmarks with
fifo_batch=32 and fifo_batch=16, but I guess that you have to currently
change the define in the source doesn't make that very likely. I don't
really like your global settings (for per-queue entities), but I guess
they can suffice until a better approach is done.
I'll do some benching today.
