From 604407890ecf624c2fb41013c82b22aade59b455 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Wed, 9 Aug 2017 11:32:11 -0700 Subject: dm: fix printk() rate limiting code Using the same rate limiting state for different kinds of messages is wrong because this can cause a high frequency message to suppress a report of a low frequency message. Hence use a unique rate limiting state per message type.
