There's a lot of work here moving sysfs logic out into a "kernfs" to allow other subsystems to also have a virtual filesystem with the same attributes of sysfs (handle device disconnect, dynamic creation / removal as needed / unneeded, etc. This is primarily being done for the cgroups filesystem, but the goal is to also move debugfs to it when it is ready, solving all of the known issues in that filesystem as well. The code isn't completed yet, but all should be stable now (there is a big section that was reverted due to problems found when testing.) There's also some other smaller fixes, and a driver core addition that allows for a "collection" of objects, that the DRM people will be using soon (it's in this tree to make merges after -rc1 easier.) All of this has been in linux-next with no reported issues.
