Hello guys, 1) If I use printk(KERN_<LEVEL>...) the checkpatch warns me: WARNING: Prefer [subsystem eg: netdev]_dbg([subsystem]dev, ... then dev_dbg(dev, ... then pr_debug(... to printk(KERN_DEBUG ... So, pr_devel() is the correct way to print a debug level msg? 2) if pr_<level> is the correct way, what about KERN_DEFAULT ? If I don't put the kern_level (printk("Hello");) WARNING: printk() should include KERN_ facility level if I put KERN_DEFAULT: WARNING: Prefer [subsystem eg: netdev]_default([subsystem]dev, ... then dev_default(dev, ... then pr_default(... to printk(KERN_DEFAULT ... But for KERN_DEFAULT, there isn't a macro pr_<level> like pr_devel(). Can anyone show me the correct way? tks
