From: Arushi Singhal Date: Mon, 12 Mar 2018 13:06:29 +0000 (+0530) Subject: netfilter: Replace printk() with pr_*() and define pr_fmt() X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5191d70f83fd1878c40029cffe69f6a2bf65fa0e;p=openwrt%2Fstaging%2Fblogic.git netfilter: Replace printk() with pr_*() and define pr_fmt() Using pr_() is more concise than printk(KERN_). This patch: * Replace printks having a log level with the appropriate pr_*() macros. * Define pr_fmt() to include relevant name. * Remove redundant prefixes from pr_*() calls. * Indent the code where possible. * Remove the useless output messages. * Remove periods from messages.
