    I was not planning to touch anything but epoll, signalfd and timerfd
    files.

    Currently, they use a single inode, and multiple dentries (to give the
    name of the class). But this could be changed to a single dentry like
    Linus was suggesting. I'll wait for Al's reply before doing anything.
    Memory saving can be something, on top of the already big one of avoiding
    code duplication.
