Subject: CLONE_THREAD issue

Hello All,

 I am testing one small module in 2.6.16 kernel, which
is intilizing one Tasklet funcion and creating one
kernel thread using kernel_thread() which is
responsible for Scheduling Tasklet, Inside the Tasklet
function I have just putted one printk statement.

I am calling Tasklet Intilization and kernel_thread
inside module init fucntion.

This is my kernel_thread function.
kernel_thread(thread_entry_point, 0,
CLONE_VM|CLONE_FS|CLONE_FILES|CLONE_SIGHAND|CLONE_THREAD)

Inside thread_entry_point I am scheduling Tasklet.

Problem is When I remove CLONE_THREAD form
kernel_thread function everything is working fine.
but with CLONE_THREAD, I am even not able to load the
module just after doing insmoe <module name> maching
get hang.

Looking for help.

Thanks,
Murtuja
