Prefix all printk/pr_ messages with "random: " to make the logging a bit more consistent. Miscellanea: o Convert a printks to pr_notice o Whitespace to align to open parentheses o Remove embedded "random: " from pr_* as pr_fmt adds it Signed-off-by: Yangtao Li Link: https://lore.kernel.org/r/20190607182517.28266-3-tiny.windzz@gmail.com Signed-off-by: Theodore Ts'o Signed-off-by: Jason A.
