Difference between a kthread and an ordinary process.

[Pranav Peshwe]

Hello,
         When a kthread is created using the kthread_create (9)
function, i found out that a new instance of struct proc is created
and allocated for the thread just as in case of a creation of a new
process.Also, the thread is assigned a pid as in the case of a
process.
  What is the difference between a kernel thread and a normal process
created using fork ? except the address space sharing with swapper and
kernel mode execution of the kthread. Is a kthread effectively just a
process always running in kernel mode ?

TIA.

Regards,
Pranav.
