Using MOBFMT_RANGE in the early days of guest backed objects was a major performance win but that has changed a lot since. There's no more a performance reason to use MOBFMT_RANGE. The device can/will still profit from the pages being contiguous but marking them as MOBFMT_RANGE no longer matters. Benchmarks (e.g. heaven, valley) show that creating page tables for mob memory is actually faster than using mobfmt ranges.

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.
