[LKDP] get exit status from kernel

[Romano Trampus]

Hi,

I'm writing a simple program running as a module. I call exec_usermodehelper
to execute an external program. I need to get the exit status of that
application. For some reason the waitpid function runs only if the "status"
argument is NULL and fail if it'a a pointer to a integer. Because the
integer is allocated in kernel space instead of user space?
Do anybody know how to make it work?

thank's a lot to all

bye
