Hi Linus,

I know this is running extremely late so I have only included bug fixes
and a few small cleanups.

In particular the cleanup
optimization: try to avoid refing the label in apparmor_file_open
is nice to have for scaling on large systems, as it avoids take a ref count when
it isn't necessary. For the file open test resulting in

kernel test robot noticed a 93.1% improvement of will-it-scale.per_process_ops on:


These patches have all been merge tested against your tree as of
this morning and regression tested against your tree as of yesterday.

thanks
- john
