The 4.3 kernel has been released

Linus has released the 4.3 kernel right onthe 63-day schedule. "So on the whole, this remains a rather calmrelease cycle until the very end. And with the release of 4.3, obviouslythe merge window for 4.4 is open, and let's keep our fingers crossed thatthat will be an equally calm release." 4.3 includes the ability toadd BPF programs to user-space probes, the "PIDs controller" (ananti-fork-bomb measure), the removal of theext3 filesystem, support for identifier locatoraddressing, the ability to handle pagefaults in user space, and more.
