>From a reviews perspective what I would want is each set of changes,
file system, networking, arch, etc split into separate patches. For
example you have a number of patches just adding header files. You could
merge the header file with the hook additions. Then you have a natural
code split up which should be easier to review..

For instance if the function name was "tomoyo_check_capable" it would be
clear that it's part of your code.. The current function naming here is
obscure ..

This printk clearly needs to go away ..
