We need to use count_swpout_vm_event() for sio_write_complete() to get
correct counting.
Note that THP swap in (if it ever happens) is current accounted 1 for each
page, whether HUGE or normal. This is different from swap-out accounting.
This patch should be squashed into
MM: handle THP in swap_*page_fs()

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.
