It's just not needed in Linux because it carefully kept it's ABI very narrow. Which means that implementations of old, obsolete and no-longer-useful interfaces comprises only tiny piece of kernel (most of these are transparently translated to new capabilities). Most programs still use open(2) and read(2) even today, you know!

So in other words an in-kernel compatibility layer. (And indeed, I was just poking about in the fsnotify/inotify code last week after I and some users hit a bug in Ubuntu's kernel.)
