[PATCH] libaudit.c - add entry list check for the path filter
The auditctl filter "path" is only valid on the exit filter list, and
the current version of auditctl does not perform this sanity check.
Other values filter options which are required to be on the exit list
have this sanity-check mechanism.
Below is a patch which adds this sanity check for the "path" filter keyword.
Thanks,
Mike
