From: Oleksandr Natalenko Date: Wed, 2 Oct 2019 11:46:10 +0000 (+0200) Subject: docs: admin-guide: fix printk_ratelimit explanation X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=ca30ad857d903a2462b85bf83357becb668f0ad7;p=openwrt%2Fstaging%2Fblogic.git 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.
