[cp-patches] FYI: epoll: deleting closed file descriptors

[Casey Marshall]

A file descriptor is removed from an epoll descriptor when it is closed;
trying to remove it later harmlessly returns ENOENT. This handles that case.

        * native/jni/java-nio/gnu_java_nio_EpollSelectorImpl.c
        (Java_gnu_java_nio_EpollSelectorImpl_epoll_1delete): ignore
        ENOENT.

Committed.
