Yeah I'm aware that it's a system call that only knows about file descriptors. It's just that it just now hit me that a consequence of that is that a web server configured to use ssl _and_ sendfile isn't really using sendfile, short of some hairy hack of writing/encrypting the response into a file (maybe in-memory with something like memfd_create) and using sendfile on that, which would defeat the purpose of avoiding user-space entirely.
