Johannes Weiner 19e5dc2e6b mm: memcontrol: clarify swapaccount=0 deprecation warning
commit 118642d7f6 upstream.

The swapaccount deprecation warning is throwing false positives.  Since we
deprecated the knob and defaulted to enabling, the only reports we've been
getting are from folks that set swapaccount=1.  While this is a nice
affirmation that always-enabling was the right choice, we certainly don't
want to warn when users request the supported mode.

Only warn when disabling is requested, and clarify the warning.

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.
