[PATCH] bug fix in kernel/kmod.c
I think there is a bug in kmod.c: In __call_usermodehelper(), when kernel_thread(wait_for_helper, ...) return success, since wait_for_helper() might call complete() at any time, the sub_info should not be used any more. Normally wait_for_helper() take a long time to finish, you may not get problem for most of the case. But if you remove /sbin/modprobe, it may become easier for you to get a oop in khelper.
