Georgi Djakov 25eaab438d mm/page_io: use pr_alert_ratelimited for swap read/write errors
If there are errors during swap read or write, they can easily fill the
log buffer and remove any previous messages that might be useful for
debugging, especially on systems that rely for logging only on the kernel
ring-buffer.

For example, on a systems using zram as swap, we are more likely to see
any page allocation errors preceding the swap write errors if the alerts
are ratelimited.

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.
