Current lightnvm and pblk implementation does not care about NVMe max data transfer size, which can be smaller than 64*K=256K. There are existing NVMe controllers which NVMe max data transfer size is lower that 256K (for example 128K, which happens for existing NVMe controllers which are NVMe spec compliant). Such a controllers are not able to handle command which contains 64 PPAs, since the the size of DMAed buffer will be above the capabilities of such a controller.
