printk(KERN_DEBUG ...) vs printk(...)
What is difference between printk(KERN_DEBUG ...) and printk( ...) ?
After I replace the latter with the former, the kernel is not dumping debug messages anymore. |
Well, I know nothing about Kernel editing so I'll take a stab at it.
The KERN_DEBUG is telling printk to print only anything related to KERN_DEBUG whereas printk with no arguments will print everything. |
