You try to call something that isn't a function. It's most likely in a situation where you have a function pointer somewhere. Double-check your code.

The code is
asmlinkage long sys_abcd(void)
{
printk("%ld",THREAD_SIZE);
}
if it is wrong can you say where is this is going wrong if it is correct then why its not working...

This looks OK, the only small thing is that it should return something.

How do you register this function as a syscall handler?

You would need to return the value you tried to printk, like so:

Code:

asmlinkage long sys_abcd(void)
{
  printk("%ld", THREAD_SIZE);
  return THREAD_SIZE;
};
