SGL size of metadata is usually small. Thus, 1 inline sg should cover most cases. The macro will be used for pre-allocate a single SGL entry for metadata. The preallocation of small inline SGLs depends on SG_CHAIN capability so if the ARCH doesn't support SG_CHAIN, use the runtime allocation for the SGL. This patch is a preparation for adding metadata (T10-PI) over fabric support.

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.
