The man pages for Linux kernel internals and syscalls are pretty good stuff like, inotify, procfs etc all have really good detailed man pages. The userland stuff is a different story. I think it is because BSD doesn't distinguish userland from kernel they are all shipped in the same package so manual pages are probably kept more consistent. Linux uses stuff like GNU etc for a lot of userland tools so it is more of a mixed bag different community different developers etc.
