    sys/security/audit   audit_syscalls.c 
  Log:
  On RELENG_6, vn_open() will drop Giant aquired for calls into
  non-MP-safe filesystem if fdx == -1, assuming the in-kernel callers are
  not MP-safe. On HEAD, vn_open() after rev. 1.240 of sys/kern/vfs_vnops.c
  would keep the Giant locked when the MPSAFE flag is given.
  
  The difference in the API caused the auditctl() syscall code to try to
  unlock non-locked Giant for non-MP-safe filesystems, for instance, UFS
  when QUOTA is compiled in.
  
  This is direct commit to RELENG_6 to accomodate for RELENG_6' vn_open().
