I assume this is a rethorical question and I notice what I suggested looks as bad as my earlier commit message :-) So, I gave it some thought that and decided to "open code" the paragraph as "Add sgx_vma_access() function that implements 'access' virtual function of struct vm_operations_struct. Use formentioned leaf instructions to achieve read and write primitives for the enclave memory." I think this starts to have the right balance and is understandable. Still open for futher suggestion of course. > -- > Regards/Gruss, > Boris. > > https://people.kernel.org/tglx/notes-about-netiquette /Jarkko
