Joonsoo Kim 0076f029cb mm/memory: fix IO cost for anonymous page 
With synchronous IO swap device, swap-in is directly handled in fault
code.  Since IO cost notation isn't added there, with synchronous IO
swap device, LRU balancing could be wrongly biased.  Fix it to count it
in fault code.

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.
