Hans de Goede 8ec08f1431 libata: add ATA_HORKAGE_NO_NCQ_TRIM for Samsung 860 and 870 SSDs
commit 8a6430ab9c9c87cb64c512e505e8690bbaee190b upstream.

Commit ca6bfcb2f6 ("libata: Enable queued TRIM for Samsung SSD 860")
limited the existing ATA_HORKAGE_NO_NCQ_TRIM quirk from "Samsung SSD 8*",
covering all Samsung 800 series SSDs, to only apply to "Samsung SSD 840*"
and "Samsung SSD 850*" series based on information from Samsung.

But there is a large number of users which is still reporting issues
with the Samsung 860 and 870 SSDs combined with Intel, ASmedia or
Marvell SATA controllers and all reporters also report these problems
going away when disabling queued trims.

Note that with AMD SATA controllers users are reporting even worse
issues and only completely disabling NCQ helps there, this will be
addressed in a separate patch.

Fixes: ca6bfcb2f6 ("libata: Enable queued TRIM for Samsung SSD 860")

README

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.
