Maybe you can explain a bit better what's this all about? Both the commit that introduces blk-mq and the paper on it talk about high IOPS devices, multi-core, NUMA systems. I'm not sure this is the case for UBI-based devices. Probably some numbers would help us decide. Does the patch increases the dynamic memory footprint? Is there any performance benefit? I kind of like the negative diffstat, but the code doesn't look cleaner or simpler. In other words, we need a good reason before we agree on making this "zen style" driver more complex. -- Ezequiel García, Free Electrons Embedded Linux, Kernel and Android Engineering http://free-electrons.com
