[PATCH] add rule filterkey
Add support for a rule key, which can be used to tie audit records to audit
rules. This is useful when a watched file is accessed through a link or
symlink, as well as for general audit log analysis.
Because this patch uses a string key instead of an integer key, there is a bit
of extra overhead to do the kstrdup() when a rule fires. However, we're also
allocating memory for the audit record buffer, so it's probably not that
significant. I went ahead with a string key because it seems more
user-friendly.
Note that the user must ensure that filterkeys are unique. The kernel only
checks for duplicate rules.
