ima: use generic_file_llseek for securityfs
Arnd Bergmann [Wed, 7 Jul 2010 21:40:15 +0000 (23:40 +0200)]
The default for llseek will change to no_llseek,
so securityfs users need to add explicit .llseek
assignments. Since we're dealing with regular
files from a VFS perspective, use generic_file_llseek.
