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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
