Yeah, I'm keeping this tree up to date:
(Though it looks like kernel.org is slow to update at the moment.)

They're in a separate tree from the main Yama work because those two
patches will never go upstream. The link restrictions patch is in the
core VFS for 3.6, so that will get dropped. The unconditional chaining
will continue to live outside mainline until there is sensible LSM
composing. Hopefully we'll make progress on that during the up-coming
Linux Security Summit.
