Linus Torvalds put out the second release candidate for the Linux 3.6 kernel
after allowing two weeks for its development but ignoring the "unnecessarily big and scary" changes.
The Linux 3.6-rc2 kernel was released after two weeks rather than one due to Linus Torvalds' travels. He was conservative in what he merged outside of the 3.6 merge window so a number of pull requests were rejected until Linux 3.7 -- he's being strict about only wanting critical fixes.
There's 330 commits for 3.6-rc2 with the changes being spread around the board but DRM/GPU and tools/perf updates standing out in particular.
