Do you need security_context_unsupported.cc?

[bkonyi, 2017/06/05 20:25:51]

secure_socket_unsupported.cc contains all of the entry points already, so this
should still work fine. However, I can split secure_socket_unsupported.cc into
secure_socket_filter_unsupported.cc and security_context_unsupported.cc if that
makes more sense.
