Linux 3.2-rc6

Linux 3.2-rc6

[Linus Torvalds]

Ok, people have clearly figured out and are gaming my release timing,
because over half the commits in -rc6 were merged today.

And that's purely because I got more merge requests today than I got
the rest of the week..

Now, I'll be somewhat generous and just say "ok, people left it to
Friday before the holidays to push me stuff", and maybe it's not
gaming the -rc cycle, but in general I *hate* it when it seems like
people leave their requests to the last moment. So if you did it
consciously, please just stop. It would be much nicer to just spread
things out, and have developers that track current -git give reactions
to things as they come in, rather than having things clump just before
the -rc release.

That said, this is still a smaller -rc release than previous ones, and
things do seem to be calming down. We're at -rc6 now, and while I can
see myself doing an -rc7, I probably won't do an -rc8 unles something
bad pops up. There doesn't seem to be any real reason to drag out this
release any more, and we'll probably have the real 3.2 around new
years.

Shortlog appended, the only thing that stands out is that we have
relatively more fs updates than usual - both btrfs and cifs had some
sizable (for -rc6) updates here, and there's a few smaller ext4
commits too. That said, it's still dominated by drivers (block - swim3
driver - and i915 - more eDP updates), just less than usual. And some
arm and x86 stuff. The rest is really tiny.

Nothing really stands out,

And the message for maintainers is:  hurry up and *DO NOT* rebase your
(linux-next included) tree!  ;-)

But *do* get all you features into linux-next now!

I'm sorry, but that's nowhere near enough.  As I said in followup to
the original posting of that patch, it still leaves a race window
where inode is already associated with dentry but still doesn't have
->a_ops, etc. set up.  Hell, ->symlink() doesn't write the symlink
body until after that point...

Thanks Al, I'll test this as well and pull it in.
