There's a rather huge patch-set out there now, taking the 2.3.x series to 2.3.15.
This has a lot of the merge code I've been sent over the last two weeks, but I will invariably have missed some, if for no other reason than simply that I got absolutely _flooded_ by people sending me patches.
One of the more interesting things was the SMP pipe cleanup sent by Richard, but try as I might it was never really stable under load on x86 - not with the plain semaphores in 2.3.14, and not with the patches Andrea had either. I assume Richard tested it on an alpha with the much more well-thought-out atomic operation that the alpha provides.
I ended up rewriting the x86 semaphore code (and some of Richards pipe code too, for that matter, to get rid of some races in waking things up), and it doesn't show the problems I saw before, but hey, maybe I just exchanged one set of problems for another set that I can't trigger any more. Give me feedback, please.
Other features that don't impact everybody, but are rather major:
