man kthread says:
The kthread_create() function is used to create a kernel thread. The new
thread shares its address space with process 0, the swapper process, and
runs in kernel mode only.
However, when i checked the pid & tid of the new created thread it was
not the same as the parent nor as the proc0 & thread0
simple printf() gives:
swap procid=0, threadid=0
procid=1680, threadid=100089
procid=1681, threadid=100090 <--- created by kthread_create()
