Subject: printk or pr_<level>?
Date: Wed, 23 Jul 2014 15:16:52 -0300 [thread overview]
Message-ID: <53CFFC14.1040803@gmail.com> (raw)
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
