Mikhail Skorzhinskii 958f2a0f81 nvme-tcp: set the STABLE_WRITES flag when data digests are enabled
There was a few false alarms sighted on target side about wrong data
digest while performing high throughput load to XFS filesystem shared
through NVMoF TCP.

This flag tells the rest of the kernel to ensure that the data buffer
does not change while the write is in flight.  It incurs a performance
penalty, so only enable it when it is actually needed, i.e. when we are
calculating data digests.

Although even with this change in place, ext2 users can steel experience
false positives, as ext2 is not respecting this flag. This may be apply
to vfat as well.

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.
