http://perforce.freebsd.org/chv.cgi?CH=102682 Change 102682 by jhb@jhb_mutex on 2006/07/28 20:11:51 Include a new set of macros: SYS_AUE_foo in sysproto.h which resolve to the audit event for syscall 'foo' and make use of this in SYSCALL_MODULE_HELPER to define the correct audit events for system calls in loadable modules (e.g. sysv IPC).
