From: Mike Rapoport <redacted> Yuri Norov says: If parameter size is the same for native and compat ABIs, we may wire a syscall made by compat client to native handler. This is true for unsigned int, but not true for unsigned long or pointer. That's why I suggest using unsigned int and so avoid creating compat entry point. Use unsigned int as the type of the flags parameter in memfd_secret() system call. Signed-off-by: Mike Rapoport <redacted>
