Linux 4.7 rc1

This time around we have a fairly big change to the vfs layer that allows filesystems (if theybuy into it) to do readdir() and path component lookup in parallelwithin the same directory.That's probably the biggest conceptual vfs change we've had since westarted doing cached pathname lookups using RCU.That said, the actual *code* changes for that all are fairly small,and are dwarfed by all the usual driver updates. In fact, none of thefilesystem updates even show up on the default "dirstat" statistics(because git dirstat by default cuts off showing things at 3%).  Sowhen it comes to the bulk of the work, we have the usual distribution:about two thirds drivers (gpu and network drivers dominate, but it'sall over) and the rest is mostly arch updates, documentation,networking, and "misc" (which is where the vfs changes are hiding).While this isn't a huge release, it's certainly big enough that eventhe shortlog is much too big to post or read to get an overview, soappended is my normal mergelog summary. And as such, remember that thepeople credited are the people I pull the changes from, which is notnecessarily at all the people who actually wrote the code.Just to give people a sense of the disparity between the maintainerlist below and the number of people submitting patches, there areabout 1400 authors in total for the stuff that came in during themerge window.Anyway, enough blathering. Go out and test. And in particular, ifyou're a low-level filesystem person, or involved in other ways inpath component lookup (security layer etc), go check that everythinglooks ok, and if your filesystem isn't one that does parallel lookupsor readdirs yet (because locking issues), take a look at that too.
