>From the initial implementation of NVMe SGL kernel support commita7a7cbe353("nvme-pci: add SGL support") with addition of the commit943e942e62("nvme-pci: limit max IO size and segments to avoid high order allocations") now there is only caller left for nvme_pci_iod_alloc_size() which statically passes true for last parameter that calculates allocation size based on SGL since we need size of biggest command supported for mempool allocation. This patch modifies the helper functions nvme_pci_iod_alloc_size() such that it is now uses maximum of PRP and SGL size for iod allocation size calculation.

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.
