The first release candidate for Linux kernel 4.2 has been released and is available for download.
Linus Torvalds quotes at the Linux kernel mailing list; “I thought this release would be one of the biggest ones ever, but it turns out that it will depend on how you count. Just counting pure commits, it is indeed one of the bigger rc1’s in recent history, but 3.10-rc1 was almost as big, and then the final 3.10 grew from that more than most. I doubt we’ll match the 3.10 release, since we have been getting progressively better at *not* merging tons of stuff after -rc1.”
