T10 PI is not a widely used feature. This has us only allocate the structs for it if the feature has been enabled. For a common small setup where you have 1 virtqueue and 128 commands per queue, this saves: 8MB = 32 bytes per sg * 2048 entries * 128 commands per vhost-scsi device.

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 reStructuredText 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.
