Ok, to be more accurate it is possible to avoid using "trusted"
framework even if the scanning is done in a different process. You just
need to make sure that the scanning process is started and registered to
the process accepting kernel events before it actually starts to
handle kernel events. On the other hand all file accesses from
the scanning process will go through process accepting kernel requests.
This leads to more context switches.


Thats right, but the question is how much is the performance
gain and if it justifies the additional code complexity. I think the most
file accesses will be done by untrusted processes and those
accesses will have to be reported to userspace anyway.
