[ Upstream commitb5fd2e00a6] A "short" ARS (address range scrub) instructs the platform firmware to return known errors. In contrast, a "long" ARS instructs platform firmware to arrange every data address on the DIMM to be read / checked for poisoned data. The conversion of the flags in commitd3abaf43ba"acpi, nfit: Fix Address Range Scrub completion tracking", changed the meaning of passing '0' to acpi_nfit_ars_rescan(). Previously '0' meant "not short", now '0' is ARS_REQ_SHORT. Pass ARS_REQ_LONG to restore the expected scrub-type behavior of user-initiated ARS sessions.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
