    sys/kern             vfs_vnops.c 
  Log:
   - Remove GIANT_REQUIRED where giant is no longer required.
   - Protect access to mnt_kern_flag with the mountpoint mutex.
   - Use the appropriate nd flags to deal with giant in vn_open_cred().
     We currently determine whether the caller is mpsafe by checking
     for a valid fdidx.  Any caller coming from user-space is now
     mpsafe and supplies a valid fd.  No kenrel callers have been
     converted to mpsafe, so this check is sufficient for now.
   - Use VFS_LOCK_GIANT instead of manual giant acquisition where
     appropriate.
