So when you add a new EPC section with sgx_setup_epc_section(), those new pages in "nr_pages" are initially not going to be accounted anywhere? Or is that sgx_nr_all_pages? And you do that in your second patch... But those new pages coming in *are* free pages so they should be in the free pages count too, IMHO. -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette
