Subject: privilege level of program which is called by call_usermodehelper()

Message-ID: <20061112190848.37896.qmail@web27401.mail.ukl.yahoo.com> (raw)
Hi,
I think the program which is called by
call_usermodehelper() will not be executed at
privilege level zero on IA-32 machines.
Am I right?
How to run a program which has been compiled by a
compiler(say gcc) at privilege level zero?
Indeed I want to compare time taken in executing two
programs. If we run them at privilege level zero by
calling them in a kernel module, processor will not
switch to other processors. So that we can find out
time taken to execute a program more accurately.
What you say??
Thanks in advance.
