function::printk - Send a message to the kernel trace buffer
an integer for the severity level (0=KERN_EMERG ... 7=KERN_DEBUG)
The formatted message string
Print a line of text to the kernel dmesg/console with the given severity. An implicit end-of-line is added. This function may not be safely called from all kernel probe contexts, so is restricted to guru mode only.
