android-cloexec-epoll-create1
=============================

``epoll_create1()`` should include ``EPOLL_CLOEXEC`` in its type argument to
avoid the file descriptor leakage. Without this flag, an opened sensitive file
would remain open across a fork+exec to a lower-privileged SELinux domain.

Examples:

.. code-block:: c++

  epoll_create1(0);

  // becomes

  epoll_create1(EPOLL_CLOEXEC);
