Hello linux-experts,
While I tried to free the memory I allocated
using kfree, I received the following error:
I am working in kernel 2.4.28.
I have also attached the code. Can anyone help me
regarding this? I have also checked for NULL pointer
even though it is not necessary.
Thanks,
selva

list_for_each(p,&rhash_table[i])
{
//printk("\n Printing details for my..");
my = list_entry(p, struct resource, res_list);
if(my)
{
printk("\n My is not null..");
printk("\n%ld,", my -> rid.fd);
printk("%ld,", my -> rid.inode);
printk("%d,", my -> rid.ACCESS_TYPE);
list_del(&my -> res_list);
kfree(my);
}

this is not allowed in list_for_each,
you must use list_for_each_safe() instead.
