Subject: [PATCH] Use up-to-date system call to create epoll context

epoll_create() is a deprecated, older variant of epoll_create1(). Older versions
of epoll_create() used to take a size argument to provide a hint about the
number of file descriptors to be watched. Nowadays the kernel dynamically sizes
the required data structures.
