Hi all, meat to the bone: with this patchset one can change the physical and logical block size of the 'brd' ramdisk driver. Default is 512 (for both); one can easily increase the physical block size to 16k and the logical block size to 4k. Increasing the logcial block size beyond 4k gives some 'interesting' crashes. It should also be possible to use the resulting ram disk as a backend for nvme target, thereby exercising the NVMe stack for larger block sizes, too. Happy hacking!
