Hmm...I don't think what we are getting is expected or useful. It would be
nice to know what the paths are instead of NULL.
Is every single record NULL? I felt like it once upon a time had some
information.... Usually these are files in debugfs and sysfs being
created by the module load.
It would also be highly
desirable to get some basic information recorded about what module is getting
loaded in an aux record.
Might be do-able to get something from the module header...
with finit_module (as opposed to init_module) we probably can get
something about the file descriptor...
Especially since loading modules are how system tap
and some of the kernel bug patching tools get loaded.
Not sure how reliable/useful these fields are, but we can possibly get
something...
