[SOLVED] Difference between printk and pr_info

Issue

What's the exact difference between printk and pr_info functions ? And under what conditions, should I choose one over the another ?

Solution

The kernel's printk.h has:

#define pr_info(fmt,arg...) \
    printk(KERN_INFO fmt,##arg)

Just like the name, pr_info is printk with the KERN_INFO priority.
