Gregory's ServerAnd note that they don't want you to know about the 8th, secret inode type! It's not mentioned in the inode(7) man page after all. But now I spilled the beans anyway!
Psst! 🤫

 @nilsding yes, a multitude of apis of the kernel expose these anonymous inodes these days. Eventfd, signalfd, epoll, inotify, and so on. Basically a good chunk of the kernel apis that give you an fd as a reference to some api object do this. Tremendously useful hence, and very common. But not particularly visible outside of programs since generally not visible in the fs except for /proc/self/fd/.  @pid_eins oooh, that makes sense actually. Never really questioned the origin of these |
@pid_eins what’s the purpose of these inodes? do they have a practical use?
