It seems that there is no more complains nor questions. Do you want me to send another series to fix the order of the S-o-b in patch 7?There is a major question regarding the API design and the choice of hooking that stuff on open(). And I have not heard anything resembling a coherent answer.
To me O_MAYEXEC is just the wrong name. The bit would be (something like) O_INTERPRET to indicate what you want to do with the contents. The kernel 'policy' then decides whether that needs 'r-x' access or whether 'r--' access in enough. I think that is what you 100 line comment in 0/n means.
