Some environments want to use a host tmpfs/ramdisk to back guest pmem. While the data is not persisted relative to the host it *is* persisted relative to guest crashes / reboots. The guest is free to use dax and MAP_SYNC to keep filesystem metadata consistent with dax accesses without requiring guest fsync(). The guest can also observe that the region is volatile and skip cache flushing as global visibility is enough to "persist" data relative to the host staying alive over guest reset events.

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.
