Hi,
The following program hangs the kernel, when the insmod on it, is run. Can any
one provide ideas why :
#include <linux/module.h> // for init_module()
#include <linux/proc_fs.h> // for create_proc_info_entry()
#include <asm/io.h> // for inb(), outb()
int my_func( char *buf, char **start, off_t off, int count, int *eof, void
*data )
{
return 0;
}
char modname[] = "cmos";
static int __init my_init( void )
{
struct proc_dir_entry *pde, *tmp;
tmp = kmalloc(sizeof(struct proc_dir_entry), GFP_KERNEL);
pde= create_proc_entry(modname, S_IFDIR | S_IRUGO | S_IXUGO , tmp);
pde->nlink = 1;
pde->read_proc = my_func;
if(pde)
printk("proc_create sucessfull name = %s\n", pde->name);
else
printk("proc_create not so sucessfull. Exiting........... \n");
return 0;
}
static void __exit my_exit(void )
{
remove_proc_entry( modname, NULL );
printk("Exiting ................\n");
}
module_init( my_init );
module_exit( my_exit );
MODULE_LICENSE("GPL");
Thanks,
Giriprasad
