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.
