loop devices under heavy stress-ng loop streessor can trigger many capacity change events in a short time. Each event prints an info message from set_capacity_and_notify(), flooding the console and contributing to soft lockups on slow consoles. Switch the printk in set_capacity_and_notify() to pr_info_ratelimited() so frequent capacity changes do not spam the log while still reporting occasional changes.

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 reStructuredText 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.
