If this was merged in patch 7 it would just include the above, right?
I don't really mind if you prefer to split it this way though and make
fewer changes in patch 7.

Could you drop the 'inline'? I don't think it's necessary for modern
compliers. do_mmap2 could drop it too.

I did have a question about the duplication in patch 7, but assuming
you still need this patch
