Linus has released the 3.19 kernel, saying "while I was tempted a couple of times to do an rc8, there really wasn't any reason for it." Significant changes in 3.19 include support for the Altera Nios II processor architecture, device tree overlay support, the ability to attach eBPF programs to sockets, disk scrubbing and replacement for RAID 5 and 6 in the Btrfs filesystem, the execveat()system call, and much more.
