hi all:
I'm confused with pr_debug. My codes is:
I'm confused with pr_debug. My codes is:
###########################################
#include <linux/module.h>
#include <linux/kernel.h>
static int __init init_page_dir(void)
{
pr_debug("Hello world\n");
return 0;
}
static void __exit exit_page_dir(void)
{
pr_debug("\nGoodbye now...\n\n");
}
MODULE_LICENSE("GPL");
module_init(init_page_dir);
module_exit(exit_page_dir);
###########################################
I make it, and insmod it. But the messages of "Hello world" don't show.
So, My question is If i want to fix it , I should set the DEFAULT_MESSAGE_LOGLEVEL and
rebuild the kernel ?
My kernel version is:2.6.18
OS is: centOS
Thank you.
