Of the three, I prefer audit_rule_transport, but it seems
unnecessarily long to me.  I suppose we could shorten it to
audit_rule_trans, but I'm not sure that's any more readable than
'xprt'.

What do you think about changing the comment to make it more
descriptive?  i.e.,

/* audit_rule_xprt is used to transport audit filter rule content
 * between kernel and userspace.  It supports filter rules with both
 * integer and string fields and corresponds with AUDIT_ADD_RULE,
 * AUDIT_DEL_RULE and AUDIT_LIST_RULES requests.
