From 5191d70f83fd1878c40029cffe69f6a2bf65fa0e Mon Sep 17 00:00:00 2001 From: Arushi Singhal Date: Mon, 12 Mar 2018 18:36:29 +0530 Subject: 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.
