I'm getting crazy,
I don't know why kern_open() works in the module's main thread, but
when I use it in another thread created by kthread_create() it crashes
the kernel ???
kernel threads may not have a file descriptor table.
so kern_open may not work on kernel processes..
(just speculating)

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
I am not sure, but sharing another process's address space doesn't have
to imply it shares the same pid, right?
