I actually don't understand your question much :-) , But, if your
meaning is communication between Kernel & user space...and you want to
know how the kernel know pid of user space process. You should read
http://www.linuxjournal.com/article/7356. Hope this help.

Hi all,
Is there a way, from within a kernel module,

call_usermodehelper is creating ?
I want to create a user space process from within
a kernel module, and be able to kill it, send signals

can I know its pid ?
thanks
