The problem is that each vendor could have introduced this change in any version of its kernel package. Probably the easiest way is trying to compile a simple module using the additional parameters and check if it compiles (using a ./configure script, perhaps). > > 2. an other user told me that his redhat kernel bet kernel doesn't export > sys_call_table anymore.

I didn't understand why do you need sys_call_table to do the proc stuff. Your new_open() function doesn't seem to do anything except calling the real open() syscall. -- Eduardo
