The only use of stream_open() upstream right now is the xenbus
conversion, and that isn't actually a bugfix, because xenbus used to
manually do that

        filp->f_mode &= ~FMODE_ATOMIC_POS; /* cdev-style semantics */

that stream_open() does.

So no, there isn't "a bunch of patches" anywhere.

There are *future* cleanups for 5.2 that will happen, and that might
have hit linux-next. And there is at least one FUSE patch (again -
pending, not upstream) that may get marked for stable.

But I see nothing right now that makes it stable material yet.
