From ca30ad857d903a2462b85bf83357becb668f0ad7 Mon Sep 17 00:00:00 2001 From: Oleksandr Natalenko Date: Wed, 2 Oct 2019 13:46:10 +0200 Subject: [PATCH] docs: admin-guide: fix printk_ratelimit explanation The printk_ratelimit value accepts seconds, not jiffies (though it is converted into jiffies internally). Update documentation to reflect this. Also, remove the statement about allowing 1 message in 5 seconds since bursts up to 10 messages are allowed by default. Finally, while we are here, mention default value for printk_ratelimit_burst too.
