TOMOYO: Explicitly set file_operations->llseek pointer.
Tetsuo Handa [Thu, 8 Jul 2010 12:57:41 +0000 (21:57 +0900)]
TOMOYO does not deal offset pointer. Thus seek operation makes
no sense. Changing default seek operation from default_llseek()
to no_llseek() might break some applications. Thus, explicitly
set noop_llseek().
