I see. [PATCH 16/18] ( http://lkml.org/lkml/2010/7/7/258 ) contains a line

   security/tomoyo/common.c                      |    1 +

but no change in the patch. Patch was too large?
Anyway, that part is no longer in security/tomoyo/common.c
and is now security/tomoyo/securityfs_if.c .
James, please apply below patch.

Subject: [PATCH] TOMOYO: Explicitly set file_operations->llseek pointer.

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().
