You all know the drill by now - another week, another rc. I'd say that
things look fairly normal at this point: it's not a big rc2, but
that's been true lately (rc3 tends to be a bit bigger - probably just
because it takes time for people to start noticing issues).
The patch statistics look fairly normal too: about half is drivers,
almost a quarter is architecture fixups, and the rest is mostly
networking and some documentation updates, but there's some core
kernel/mm/fs fixes in there too.
The shortlog is appended and gives a good flavor of the kinds of
changes we have.
Go out and test, nothing looks all that scary there.
