Here is a revised patch that is more like I'd expect to land upstream. Jens are you OK with us adding bio_is_zero_filled to block/bio.c? If so should I split it out as a separate patch for you to pick up or just carry it as part of the patch that lands in linux-dm.git?
Yeah I'm fine with adding that helper. I do wonder what the performance impact is on this for dm. Have you tried a (worst case) test of writing blocks that are zero filled, but with the last byte not being a zero?
