commit 3179a5f7f86bcc3acd5d6fb2a29f891ef5615852 upstream. 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.
